The current flush() helper only shows the queued diff but
does not clear the queue. This is conceptually a bug, but it
works because we only call it once at the end of the
program.
Let's teach it to clear the queue, which will let us use it
in more places (one for now, but more in future patches).

Our tests send git's output directly to files or pipes, so
there will never be any color. Let's do at least one --color
test to make sure that we can handle this case (which we
currently can, but will be an easy thing to mess up when we
touch the graph code in a future patch).
We'll just cover the --graph case, since this is much more
complex than the earlier cases (i.e., if it manages to
highlight, then the non-graph case definitely would).

The graph test in t9400 covers the case of two simultaneous
branches, but all of the commits during this time are on the
right-hand branch. So we test a graph structure like:
| |
| * commit ...
| |
but we never see the reverse, a commit on the left-hand
branch:
| |
* | commit ...
| |
Since this is an easy thing to get wrong when touching the
graph-matching code, let's cover it by adding one more
commit with its timestamp interleaved with the other branch.
Note that we need to pass --date-order to convince Git to
show it this way (since --topo-order tries to keep lines of
history separate).

The exact ordering output by Git may depend on the commit

monotonically increasing, and not all the same (or worse,
subject to how long the test script takes to run).
Let's use test_tick to make sure this is stable. Note that
we actually have to rearrange the order of the branches to
match the expected graph structure (which means that
previously we might racily have been testing a slightly
different output, though the test is written in such a way

Move the Git::Error and Git::Mail::Address wrappers to the
Git::LoadCPAN::Loader::* namespace, e.g. Git::LoadCPAN::Error. That
module will then either load Error from CPAN (if installed on the OS),
or use Git::FromCPAN::Error.
When I added the Error wrapper in 20d2a30f8f ("Makefile: replace
perl/Makefile.PL with simple make rules", 2017-12-10) I didn't think
about how confusing it would be to have these modules sitting in the
same tree as our normal modules. Let's put these all into
Git::{Load,From}CPAN::* to clearly distinguish them from the rest.

The new command `git rebase --show-current-patch` is useful for seeing

This command allows to delete a worktree. Like 'move' you cannot
remove the main worktree, or one with submodules inside [1].
For deleting $GIT_WORK_TREE, Untracked files or any staged entries are
considered precious and therefore prevent removal by default. Ignored
files are not precious.
When it comes to deleting $GIT_DIR, there's no "clean" check because
there should not be any valuable data in there, except:
- HEAD reflog. There is nothing we can do about this until somebody
steps up and implements the ref graveyard.
- Detached HEAD. Technically it can still be recovered. Although it
may be nice to warn about orphan commits like 'git checkout' does.
[1] We do 'git status' with --ignore-submodules=all for safety
anyway. But this needs a closer look by submodule people before we
can allow deletion. For example, if a submodule is totally clean,
but its repo not absorbed to the main .git dir, then deleting
worktree also deletes the valuable .submodule repo too.

This command allows to relocate linked worktrees. Main worktree cannot
(yet) be moved.
There are two options to move the main worktree, but both have
complications, so it's not implemented yet. Anyway the options are:
- convert the main worktree to a linked one and move it away, leave
the git repository where it is. The repo essentially becomes bare
after this move.
- move the repository with the main worktree. The tricky part is make
sure all file descriptors to the repository are closed, or it may
fail on Windows.

Add a --prune-tags option to git-fetch, along with fetch.pruneTags
config option and a -P shorthand (-p is --prune). This allows for
doing any of:
git fetch -p -P
git fetch --prune --prune-tags
git fetch -p -P origin
git fetch --prune --prune-tags origin
Or simply:
git config fetch.prune true &&
git config fetch.pruneTags true &&
git fetch
Instead of the much more verbose:
git fetch --prune origin 'refs/tags/*:refs/tags/*' '+refs/heads/*:refs/remotes/origin/*'
Before this feature it was painful to support the use-case of pulling
from a repo which is having both its branches *and* tags deleted
regularly, and have our local references to reflect upstream.
At work we create deployment tags in the repo for each rollout, and
there's *lots* of those, so they're archived within weeks for
performance reasons.
Without this change it's hard to centrally configure such repos in
/etc/gitconfig (on servers that are only used for working with
them). You need to set fetch.prune=true globally, and then for each
repo:
git -C {} config --replace-all remote.origin.fetch "refs/tags/*:refs/tags/*" "^\+*refs/tags/\*:refs/tags/\*$"
Now I can simply set fetch.pruneTags=true in /etc/gitconfig as well,
and users running "git pull" will automatically get the pruning
semantics I want.
Even though "git remote" has corresponding "prune" and "update
--prune" subcommands I'm intentionally not adding a corresponding
prune-tags or "update --prune --prune-tags" mode to that command.
It's advertised (as noted in my recent "git remote doc: correct
dangerous lies about what prune does") as only modifying remote
tracking references, whereas any --prune-tags option is always going
to modify what from the user's perspective is a local copy of the tag,
since there's no such thing as a remote tracking tag.
Ideally add_prune_tags_to_fetch_refspec() would be something that
would use ALLOC_GROW() to grow the 'fetch` member of the 'remote'
struct. Instead I'm realloc-ing remote->fetch and adding the
tag_refspec to the end.
The reason is that parse_{fetch,push}_refspec which allocate the
refspec (ultimately remote->fetch) struct are called many places that
don't have access to a 'remote' struct. It would be hard to change all
their callsites to be amenable to carry around the bookkeeping
variables required for dynamic allocation.
All the other callers of the API first incrementally construct the
string version of the refspec in remote->fetch_refspec via
add_fetch_refspec(), before finally calling parse_fetch_refspec() via
some variation of remote_get().
It's less of a pain to deal with the one special case that needs to
modify already constructed refspecs than to chase down and change all
the other callsites. The API I'm adding is intentionally not
generalized because if we add more of these we'd probably want to
re-visit how this is done.
See my "Re: [BUG] git remote prune removes local tags, depending on
fetch config" (87po6ahx87.fsf@evledraar.gmail.com;

There's a rule in strbuf.cocci for converting trivial uses of
strbuf_addf() to strbuf_addstr() in order to simplify the code and
improve performance a bit. Coccinelle 1.0.0~rc19.deb-3 on Travis CI
lets the "%s" in that rule match format strings like "%d" as well for
some reason, though, leading to invalid proposed patches.
Use the "format" keyword to let Coccinelle parse the format string and
match the conversion specifier with a trivial regular expression
instead. This works fine with both Coccinelle 1.0.0~rc19.deb-3 and
1.0.4.deb-3+b3 (the current version on Debian testing).

Replace the perl/Makefile.PL and the fallback perl/Makefile used under
NO_PERL_MAKEMAKER=NoThanks with a much simpler implementation heavily
inspired by how the i18n infrastructure's build process works[1].
The reason for having the Makefile.PL in the first place is that it
was initially[2] building a perl C binding to interface with libgit,
this functionality, that was removed[3] before Git.pm ever made it to
the master branch.
We've since since started maintaining a fallback perl/Makefile, as
MakeMaker wouldn't work on some platforms[4]. That's just the tip of
the iceberg. We have the PM.stamp hack in the top-level Makefile[5] to
detect whether we need to regenerate the perl/perl.mak, which I fixed
just recently to deal with issues like the perl version changing from
under us[6].
There is absolutely no reason for why this needs to be so complex
anymore. All we're getting out of this elaborate Rube Goldberg machine
was copying perl/* to perl/blib/* as we do a string-replacement on
the *.pm files to hardcode @@LOCALEDIR@@ in the source, as well as
pod2man-ing Git.pm & friends.
So replace the whole thing with something that's pretty much a copy of
how we generate po/build/**.mo from po/*.po, just with a small sed(1)
command instead of msgfmt. As that's being done rename the files
from *.pm to *.pmc just to indicate that they're generated (see
"perldoc -f require").
While I'm at it, change the fallback for Error.pm from being something
where we'll ship our own Error.pm if one doesn't exist at build time
to one where we just use a Git::Error wrapper that'll always prefer
the system-wide Error.pm, only falling back to our own copy if it
really doesn't exist at runtime. It's now shipped as
Git::FromCPAN::Error, making it easy to add other modules to
Git::FromCPAN::* in the future if that's needed.
Functional changes:
* This will not always install into perl's idea of its global
"installsitelib". This only potentially matters for packagers that
need to expose Git.pm for non-git use, and as explained in the
INSTALL file there's a trivial workaround.
* The scripts themselves will 'use lib' the target directory, but if
INSTLIBDIR is set it overrides it. It doesn't have to be this way,
it could be set in addition to INSTLIBDIR, but my reading of [7] is
that this is the desired behavior.
* We don't build man pages for all of the perl modules as we used to,
only Git(3pm). As discussed on-list[8] that we were building
installed manpages for purely internal APIs like Git::I18N or
private-Error.pm was always a bug anyway, and all the Git::SVN::*
ones say they're internal APIs.
There are apparently external users of Git.pm, but I don't expect
there to be any of the others.
As a side-effect of these general changes the perl documentation
now only installed by install-{doc,man}, not a mere "install" as
before.

When we specify a list of namespaces to fetch from, by default the MW
API will not fetch from the default namespace, refered to as "(Main)"
in the documentation:
https://www.mediawiki.org/wiki/Manual:Namespace#Built-in_namespaces
I haven't found a way to address that "(Main)" namespace when getting
the namespace ids: indeed, when listing namespaces, there is no
"canonical" field for the main namespace, although there is a "*"
field that is set to "" (empty). So in theory, we could specify the
empty namespace to get the main namespace, but that would make
specifying namespaces harder for the user: we would need to teach
users about the "empty" default namespace. It would also make the code
more complicated: we'd need to parse quotes in the configuration.
So we simply override the query here and allow the user to specify
"(Main)" since that is the publicly documented name.

The diff-so-fancy project is also written in perl, and most

single script. So let's pull most of diff-highlight's code
into its own module which can be used by diff-so-fancy.
In addition, we'll abstract a few basic items like reading
from stdio so that a script using the module can do more
processing before or after diff-highlight handles the lines.

One small downside is that the diff-highlight script must

If a URL rewrite switches the protocol to something

It would be nice if we could make this work out of the box,

Add a --no-tags option to clone without fetching any tags.
Without this change there's no easy way to clone a repository without
also fetching its tags.
When supplying --single-branch the primary remote branch will be
cloned, but in addition tags will be followed & retrieved. Now
--no-tags can be added --single-branch to clone a repository without
tags, and which only tracks a single upstream branch.
This option works without --single-branch as well, and will do a
normal clone but not fetch any tags.
Many git commands pay some fixed overhead as a function of the number
of references. E.g. creating ~40k tags in linux.git will cause a
command like `git log -1 >/dev/null` to run in over a second instead
of in a matter of milliseconds, in addition numerous other things will
slow down, e.g. "git log <TAB>" with the bash completion will slowly
show ~40k references instead of 1.
The user might want to avoid all of that overhead to simply use a
repository like that to browse the "master" branch, or something like
a CI tool might want to keep that one branch up-to-date without caring
about any other references.
Without this change the only way of accomplishing this was either by
manually tweaking the config in a fresh repository:
git init git &&
cat >git/.git/config <<EOF &&
[remote "origin"]
url = git@github.com:git/git.git
tagOpt = --no-tags
fetch = +refs/heads/master:refs/remotes/origin/master
[branch "master"]
remote = origin
merge = refs/heads/master
EOF
cd git &&
git pull
Which requires hardcoding the "master" name, which may not be the main
--single-branch would have retrieved, or alternatively by setting
tagOpt=--no-tags right after cloning & deleting any existing tags:
git clone --single-branch git@github.com:git/git.git &&
cd git &&
git config remote.origin.tagOpt --no-tags &&
git tag -l | xargs git tag -d
Which of course was also subtly buggy if --branch was pointed at a
tag, leaving the user in a detached head:
git clone --single-branch --branch v2.12.0 git@github.com:git/git.git &&
cd git &&
git config remote.origin.tagOpt --no-tags &&
git tag -l | xargs git tag -d
Now all this complexity becomes the much simpler:
git clone --single-branch --no-tags git@github.com:git/git.git
Or in the case of cloning a single tag "branch":
git clone --single-branch --branch v2.12.0 --no-tags git@github.com:git/git.git

When we complete branch names for "git checkout", we also
complete remote branch names that could trigger the DWIM
behavior. Depending on your workflow and project, this can
be either convenient or annoying.
For instance, my clone of gitster.git contains 74 local
"jk/*" branches, but origin contains another 147. When I
want to checkout a local branch but can't quite remember the
name, tab completion shows me 251 entries. And worse, for a
topic that has been picked up for pu, the upstream branch
name is likely to be similar to mine, leading to a high
probability that I pick the wrong one and accidentally
create a new branch.
This patch adds a way for the user to tell the completion
code not to include DWIM suggestions for checkout. This can
already be done by typing:
git checkout --no-guess jk/<TAB>
but that's rather cumbersome. The downside, of course, is
that you no longer get completion support when you _do_ want
to invoke the DWIM behavior. But depending on your workflow,
that may not be a big loss (for instance, in git.git I am
much more likely to want to detach, so I'd type "git
checkout origin/jk/<TAB>" anyway).

Change the tag, branch & for-each-ref commands to have a --no-contains
option in addition to their longstanding --contains options.
This allows for finding the last-good rollout tag given a known-bad
<commit>. Given a hypothetically bad commit cf5c7253e0, the git
version to revert to can be found with this hacky two-liner:
(git tag -l 'v[0-9]*'; git tag -l --contains cf5c7253e0 'v[0-9]*') |
sort | uniq -c | grep -E '^ *1 ' | awk '{print $2}' | tail -n 10
With this new --no-contains option the same can be achieved with:
git tag -l --no-contains cf5c7253e0 'v[0-9]*' | sort | tail -n 10
As the filtering machinery is shared between the tag, branch &
for-each-ref commands, implement this for those commands too. A
practical use for this with "branch" is e.g. finding branches which
were branched off between v2.8.0 and v2.10.0:
git branch --contains v2.8.0 --no-contains v2.10.0
The "describe" command also has a --contains option, but its semantics
are unrelated to what tag/branch/for-each-ref use --contains for. A
--no-contains option for "describe" wouldn't make any sense, other
than being exactly equivalent to not supplying --contains at all,
which would be confusing at best.
Add a --without option to "tag" as an alias for --no-contains, for
consistency with --with and --contains. The --with option is
undocumented, and possibly the only user of it is
Junio (<xmqqefy71iej.fsf@gitster.mtv.corp.google.com>). But it's
trivial to support, so let's do that.
The additions to the the test suite are inverse copies of the
corresponding --contains tests. With this change --no-contains for
tag, branch & for-each-ref is just as well tested as the existing
--contains option.
In addition to those tests, add a test for "tag" which asserts that
--no-contains won't find tree/blob tags, which is slightly
unintuitive, but consistent with how --contains works & is documented.

__gitcomp_nl() iterates over all the possible completion words it gets
as argument
- filtering matching words,
- appending a trailing space to each matching word (in all but two
cases),
- prepending a prefix to each matching word (when completing words
after e.g. '--option=<TAB>' or 'master..<TAB>'), and
- adding each matching word to the COMPREPLY array.
This takes a while when a lot of refs are passed to __gitcomp_nl().
The previous changes in this series ensure that __git_refs() lists
only refs matching the current word to be completed, making a second
filtering in __gitcomp_nl() redundant.
Adding the necessary prefix and suffix could be done in __git_refs()
as well:
- When refs come from 'git for-each-ref', then that prefix and
suffix could be added much more efficiently using a 'git
for-each-ref' format containing said prefix and suffix. Care
should be taken, though, because that prefix might contain
'for-each-ref' format specifiers as part of the left hand side of
a '..' range or '...' symmetric difference notation or
fetch/push/etc. refspec, e.g. 'git log "evil-%(refname)..br<TAB>'.
Doubling every '%' in the prefix will prevent 'git for-each-ref'
from interpolating any of those contained specifiers.
- When refs come from 'git ls-remote', then that prefix and suffix
can be added in the shell loop that has to process 'git
ls-remote's output anyway.
- Finally, the prefix and suffix can be added to that handful of
potentially matching symbolic and pseudo refs right away in the
shell loop listing them.
And then all what is still left to do is to assign a bunch of
newline-separated words to a shell array, which can be done without a
shell loop iterating over each word, basically making all of
__gitcomp_nl() unnecessary for refs completion.
Add the helper function __gitcomp_direct() to fill the COMPREPLY array
with prefiltered and preprocessed words without any additional
processing, without a shell loop, with just one single compound
assignment. Modify __git_refs() to accept prefix and suffix
parameters and add them to each and every listed ref as described
above. Modify __git_complete_refs() to pass the prefix and suffix
parameters to __git_refs() and to feed __git_refs()'s output to
__gitcomp_direct() instead of __gitcomp_nl().

When completing refs, several __git_refs() code paths list all the
refs from the refs/{heads,tags,remotes}/ hierarchy and then
__gitcomp_nl() iterates over those refs in a shell loop to filter out
refs not matching the current ref to be completed. This comes with a
considerable performance penalty when a repository contains a lot of
refs but the current ref can be uniquely completed or when only a
handful of refs match the current ref.
Reduce the number of iterations in __gitcomp_nl() from the number of
refs to the number of matching refs by specifying appropriate globbing
patterns to 'git for-each-ref' and 'git ls-remote' to list only those
refs that match the current ref to be completed. However, do so only
when the ref to match is explicitly given as parameter, because the
current word on the command line might contain a prefix like
'--option=' or 'branch..'. The __git_complete_refs() and
__git_complete_fetch_refspecs() helpers introduced previously in this
patch series already call __git_refs() specifying this current ref
parameter, so all their callsites, i.e. all places in the completion
script doing refs completion, can benefit from this optimization.
Furthermore, list only those symbolic and pseudo refs that match the

When the completion script lists short refs it does so using the 'git
for-each-ref' format 'refname:short', which makes sure that all listed
refs are unambiguous. While disambiguating refs is technically
correct in this case, as opposed to the cases discussed in the
previous patch, this disambiguation involves several stat() syscalls
for each ref, thus, unfortunately, comes at a steep cost especially on
Windows and/or when there are a lot of refs to be listed. A user of
Git for Windows reported[1] 'git checkout <TAB>' taking ~11 seconds in
a repository with just about 4000 refs.
However, it's questionable whether ambiguous refs are really that bad
to justify that much extra cost:
- Ambiguous refs are not that common,
- even if a repository contains ambiguous refs, they only hurt when
the user actually happens to want to do something with one of the
ambiguous refs, and
- the issue can be easily circumvented by renaming those ambiguous
refs.
- On the other hand, apparently not that many refs are needed to
make refs completion unacceptably slow on Windows,
- and this slowness bites each and every time the user attempts refs
completion, even when the repository doesn't contain any ambiguous
refs.
- Furthermore, circumventing the issue might not be possible or
might be considerably more difficult and requires various
trade-offs (e.g. working in a repository with only a few selected
important refs while keeping a separate repository with all refs
for reference).
Arguably, in this case the benefits of technical correctness are
rather minor compared to the price we pay for it, and we are better
off opting for performance over correctness.
Use the 'git for-each-ref' format 'refname:strip=2' to list short refs
to spare the substantial cost of disambiguating.
This speeds up refs completion considerably. Uniquely completing a
branch in a repository with 100k local branches, all packed, best of
five:

When the completion script has to list only tags or only branches, it
uses the 'git for-each-ref' format 'refname:short', which makes sure
that all listed tags and branches are unambiguous. However,
disambiguating tags and branches in these cases is wrong, because:
- __git_tags(), the helper function listing possible tagname
arguments for 'git tag', lists an ambiguous tag
'refs/tags/ambiguous' as 'tags/ambiguous'. Its only consumer,
'git tag' expects its tagname argument to be under 'refs/tags/',
thus it interprets that abgiguous tag as
'refs/tags/tags/ambiguous'. Clearly wrong.
- __git_heads() lists possible branchname arguments for 'git branch'
and possible 'branch.<branchname>' configuration subsections.
Both of these expect branchnames to be under 'refs/heads/' and
misinterpret a disambiguated branchname like 'heads/ambiguous'.
Furthermore, disambiguation involves several stat() syscalls for each
tag or branch, thus comes at a steep cost especially on Windows and/or
when there are a lot of tags or branches to be listed.
Use the 'git for-each-ref' format 'refname:strip=2' instead of
'refname:short' to avoid harmful disambiguation of tags and branches
in __git_tags() and __git_heads().

Commit 49416ad22 (completion: support excluding refs, 2016-08-24) made
possible to complete short refs with a '^' prefix.
Extend the support to full refs to make completing '^refs/...' work.

After 'git fetch <remote> <TAB>' our completion script offers refspecs
that will fetch to a local branch with the same name as in the remote
repository, e.g. 'master:master'. This also completes
non-fast-forward refspecs, i.e. after a '+' prefix like
'+master:master', and fully qualified refspecs, e.g.
'refs/heads/master:refs/heads/master'. However, it does not complete
non-fast-forward fully qualified refspecs (or fully qualified refspecs
following any other prefix, e.g. '--option=', though currently no git
command supports such an option, but third party git commands might).
These refspecs are listed by the __git_refs2() function, which is just
a thin wrapper iterating over __git_refs()'s output, turning each
listed ref into a refspec. Now, it's certainly possible to modify
__git_refs2() and its callsite to pass an extra parameter containing
only the ref part of the current word to be completed (to follow suit
of the previous commit) to deal with prefixed fully qualified refspecs
as well. Unfortunately, keeping the current behavior unchanged in the
"no extra parameter" case brings in a bit of subtlety, which makes the
resulting code ugly and compelled me to write a 8-line long comment in
the proof of concept. Not good. However, since the callsite has to
be modified for proper functioning anyway, we might as well leave
__git_refs2() as is and introduce a new helper function without
backwards compatibility concerns.
Add the new function __git_complete_fetch_refspecs() that has all the
necessary parameters to do the right thing in all cases mentioned
above, including non-fast-forward fully qualified refspecs. This new
function can also easier benefit from optimizations coming later in
this patch series.

Completing full refs currently only works when the full ref stands on
in its own on the command line, but doesn't work when the current word
to be completed contains a prefix before the full ref, e.g.
'--option=refs/<TAB>' or 'master..refs/bis<TAB>'.
The reason is that __git_refs() looks at the current word to be
completed ($cur) as a whole to decide whether it has to list full (if
it starts with 'refs/') or short refs (otherwise). However, $cur also
holds said '--option=' or 'master..' prefixes, which of course throw
off this decision. Luckily, the default action is to list short refs,
that's why completing short refs happens to work even after a
'master..<TAB>' prefix and similar cases.
Pass only the ref part of the current word to be completed to
__git_refs() as a new positional parameter, so it can make the right
decision even if the whole current word contains some kind of a
prefix.
Make this new parameter the 4. positional parameter and leave the 3.
as an ignored placeholder for now (it will be used later in this patch
series).

__git_refs() currently accepts two optional positional parameters: a
remote and a flag for 'git checkout's tracking DWIMery. To fix a
minor bug, and, more importantly, for faster refs completion, this
series will add three more parameters: a prefix, the current word to
be completed and a suffix, i.e. the options accepted by __gitcomp() &
friends, and will change __git_refs() to list only refs matching that
given current word and to add that given prefix and suffix to the
listed refs.
However, __git_refs() is the helper function that is most likely used
in users' custom completion scriptlets for their own git commands, and
we don't want to break those, so
- we can't change __git_refs()'s default output format, i.e. we
can't by default append a trailing space to every listed ref,
meaning that the suffix parameter containing the default trailing
space would have to be specified on every invocation, and
- we can't change the position of existing positional parameters
either, so there would have to be plenty of set-but-empty
placeholder positional parameters all over the completion script.
Furthermore, with five positional parameters it would be really hard
to remember which position means what.
To keep callsites simple, add the new wrapper function
__git_complete_refs() around __git_refs(), which:
- instead of positional parameters accepts real '--opt=val'-style
options and with minimalistic option parsing translates them to
__git_refs()'s and __gitcomp_nl()'s positional parameters, and
- includes the '__gitcomp_nl "$(__git_refs ...)" ...' command
substitution to make its behavior match its name and the behavior
of other __git_complete_* functions, and to limit future changes
in this series to __git_refs() and this new wrapper function.
Call this wrapper function instead of __git_refs() wherever possible
throughout the completion script, i.e. when __git_refs()'s output is
fed to __gitcomp_nl() right away without further processing, which
means all callsites except a single one in the __git_refs2() helper.

There is no need for Python only to give a few messages to the
standard error stream, but we somehow did.
* ss/remote-bzr-hg-placeholder-wo-python:

An helper function to make it easier to append the result from
real_path() to a strbuf has been added.
* rs/strbuf-add-real-path:
strbuf: add strbuf_add_real_path()
cocci: use ALLOC_ARRAY
It does not make sense for these placeholder scripts to depend on Python
just because the real scripts do. At the example of Git for Windows, we
would not even be able to see those warnings as it does not ship with
Python. So just use plain shell scripts instead.
