The old behavior of "fetch --prune" was to prune whatever was being
fetched. In particular, "fetch --prune --tags" caused tags not only
to be fetched, but also to be pruned. This is inappropriate because
there is only one tags namespace that is shared among the local
repository and all remotes. Therefore, if the user defines a local
tag and then runs "git fetch --prune --tags", then the local tag is
deleted. Moreover, "--prune" and "--tags" can also be configured via
fetch.prune / remote.<name>.prune and remote.<name>.tagopt, making it
even less obvious that an invocation of "git fetch" could result in
tag lossage.
Since the command "git remote update" invokes "git fetch", it had the
same problem.
The command "git remote prune", on the other hand, disregarded the
setting of remote.<name>.tagopt, and so its behavior was inconsistent
with that of the other commands.
So the old behavior made it too easy to lose tags. To fix this
problem, change "fetch --prune" to prune references based only on
refspecs specified explicitly by the user, either on the command line
or via remote.<name>.fetch. Thus, tags are no longer made subject to
pruning by the --tags option or the remote.<name>.tagopt setting.
However, tags *are* still subject to pruning if they are fetched as
part of a refspec, and that is good. For example:
* On the command line,
git fetch --prune 'refs/tags/*:refs/tags/*'
causes tags, and only tags, to be fetched and pruned, and is
therefore a simple way for the user to get the equivalent of the old
behavior of "--prune --tag".
* For a remote that was configured with the "--mirror" option, the
configuration is set to include
[remote "name"]
fetch = +refs/*:refs/*
, which causes tags to be subject to pruning along with all other
references. This is the behavior that will typically be desired for
a mirror.

Previously, fetch's "--tags" option was considered equivalent to
specifying the refspec "refs/tags/*:refs/tags/*" on the command line;
in particular, it caused the remote.<name>.refspec configuration to be
ignored.
But it is not very useful to fetch tags without also fetching other
references, whereas it *is* quite useful to be able to fetch tags *in
addition to* other references. So change the semantics of this option
to do the latter.
If a user wants to fetch *only* tags, then it is still possible to
specifying an explicit refspec:
git fetch <remote> 'refs/tags/*:refs/tags/*'
Please note that the documentation prior to 1.8.0.3 was ambiguous
about this aspect of "fetch --tags" behavior. Commit
f0cb2f137c 2012-12-14 fetch --tags: clarify documentation
made the documentation match the old behavior. This commit changes
the documentation to match the new behavior.

The old code processed (tags == TAGS_SET) before adding the entries
used to opportunistically update references mentioned on the command
line. The result was that all tags were also considered candidates
for opportunistic updating.
This is harmless for two reasons: (a) because it would only add
entries if there is a configured refspec that covers tags *and* both
--tags and another refspec appear on the command-line; (b) because any
extra entries would be deleted later by the call to
ref_remove_duplicates() anyway.
But, to avoid extra work and extra memory usage, and to make the
implementation better match the intention, change the algorithm
slightly: compute the opportunistic refspecs based only on the
command-line arguments, storing the results into a separate temporary
list. Then add the tags (which have to come earlier in the list so
that they are not de-duped in favor of an opportunistic entry). Then
concatenate the temporary list onto the main list.
This change will also make later changes easier.

Currently, we only try converting argv[1] from "-" into "@{-1}". This
means we do not notice "-" when used together with an option. Worse,
when "git cherry-pick" is run with no options, we segfault. Fix this
by doing the substitution after we have checked that there is
something in argv to cherry-pick and know any remaining options are
meant for the revision-listing machinery.
This still does not handle "-" after the first non-cherry-pick option.
For example,
git cherry-pick foo~2 - bar~5
and
git cherry-pick --no-merges -
will still dump usage.

Most of git's traversals are robust against minor breakages
in commit data. For example, "git log" will still output an
entry for a commit that has a broken encoding or missing
author, and will not abort the whole operation.
Shortlog, on the other hand, will die as soon as it sees a
commit without an author, meaning that a repository with
a broken commit cannot get any shortlog output at all.
Let's downgrade this fatal error to a warning, and continue
the operation.
We simply ignore the commit and do not count it in the total
(since we do not have any author under which to file it).
Alternatively, we could output some kind of "<empty>" record
to collect these bogus commits. It is probably not worth it,
though; we have already warned to stderr, so the user is
aware that such bogosities exist, and any placeholder we
came up with would either be syntactically invalid, or would
potentially conflict with real data.

A clone will always create a transport struct, whether we
are cloning locally or using an actual protocol. In the
local case, we only use the transport to get the list of
refs, and then transfer the objects out-of-band.
However, there are many options that we do not bother
setting up in the local case. For the most part, these are
noops, because they only affect the object-fetching stage
(e.g., the --depth option). However, some options do have a
visible impact. For example, giving the path to upload-pack
via "-u" does not currently work for a local clone, even
though we need upload-pack to get the ref list.
We can just drop the conditional entirely and set these
options for both local and non-local clones. Rather than
keep track of which options impact the object versus the ref
fetching stage, we can simply let the noops be noops (and
the cost of setting the options in the first place is not
high).
The one exception is that we also check that the transport
provides both a "get_refs_list" and a "fetch" method. We
will now be checking the former for both cases (which is
good, since a transport that cannot fetch refs would not
work for a local clone), and we tweak the conditional to
check for a "fetch" only when we are non-local.

When stderr does not point to a tty, we typically suppress
"we are now in this phase" progress reporting (e.g., we ask
the server not to send us "counting objects" and the like).
The new "checking connectivity" message is in the same vein,
and should be suppressed. Since clone relies on the
transport code to make the decision, we can simply sneak a
peek at the "progress" field of the transport struct. That
properly takes into account both the verbosity and progress
options we were given, as well as the result of isatty().
Note that we do not set up that progress flag for a local
clone, as we do not fetch using the transport at all. That's
acceptable here, though, because we also do not perform a
connectivity check in that case.

Putting messages like "Cloning into.." and "done" on stdout
is un-Unix and uselessly clutters the stdout channel. Send
them to stderr.
We have to tweak two tests to accommodate this:
1. t5601 checks for doubled output due to forking, and
doesn't actually care where the output goes; adjust it
to check stderr.
2. t5702 is trying to test whether progress output was
sent to stderr, but naively does so by checking
whether stderr produced any output. Instead, have it
look for "%", a token found in progress output but not
elsewhere (and which lets us avoid hard-coding the
progress text in the test).
This should not regress any scripts that try to parse the
current output, as the output is already internationalized
and therefore unstable.

When using tab-completion, a directory path will often end with a
trailing slash which currently confuses "git reset" when dealing with
submodules. Now that we have parse_pathspec we can easily handle this
by simply adding the PATHSPEC_STRIP_SUBMODULE_SLASH_CHEAP flag.
To do this, we need to move the read_cache() call before the
parse_pathspec() call. All of the existing paths through cmd_reset()
that do not die early already call read_cache() at some point, so there
is no performance impact to doing this in the common case.

check-ignore currently shows how .gitignore rules would treat untracked
paths. Tracked paths do not generate useful output. This prevents
debugging of why a path became tracked unexpectedly unless that path is
first removed from the index with `git rm --cached <path>`.
The option --no-index tells the command to bypass the check for the
path being in the index and hence allows tracked paths to be checked
too.
Whilst this behaviour deviates from the characteristics of `git add` and
`git status` its use case is unlikely to cause any user confusion.
Test scripts are augmented to check this option against the standard
ignores to ensure correct behaviour.

Most status hints were written to be accurate when running "git status"
before running a commit. Many of them are not applicable when the commit
has already been started, and should not be shown in COMMIT_EDITMSG. The
most obvious are hints advising to run "git commit",
"git rebase/am/cherry-pick --continue", which do not make sense when the
command has already been run.
Other messages become slightly inaccurate (e.g. hint to use "git add" to
add untracked files), as the suggested commands are not immediately
applicable during the editing of COMMIT_EDITMSG, but would be applicable
if the commit is aborted. These messages are both potentially helpful and
slightly misleading. This patch chose to remove them too, to avoid
introducing too much complexity in the status code.
