strbuf_check_branch_ref() is the central place where many codepaths
see if a proposed name is suitable for the name of a branch. It was
designed to allow us to get stricter than the check_refname_format()
check used for refnames in general, and we already use it to reject
a branch whose name begins with a '-'. The function gets a strbuf
and a string "name", and returns non-zero if the name is not
appropriate as the name for a branch. When the name is good, it
places the full refname for the branch with the proposed name in the
strbuf before it returns.
However, it turns out that one caller looks at what is in the strbuf
even when the function returns an error. Make the function populate
the strbuf even when it returns an error. That way, when "-dash" is
given as name, "refs/heads/-dash" is placed in the strbuf when
returning an error to copy_or_rename_branch(), which notices that
the user is trying to recover with "git branch -m -- -dash dash" to
rename "-dash" to "dash".
While at it, use the same mechanism to also reject "HEAD" as a
branch name.

If an empty string is passed to link_alt_odb_entries(), our
loop finds no entries and we link nothing. But we still do
some preparatory work to normalize the object directory
path, even though we'll never look at the result. This
triggers in basically every git process, since we feed the
usually-empty ALTERNATE_DB_ENVIRONMENT to the function.
Let's detect early that there's nothing to do and return.
While we're at it, let's treat NULL the same as an empty
string as a favor to our callers. That saves
prepare_alt_odb() from having to cover this case.

The SubmittingPatches document is often cited by outside parties as an
example of good practices to follow, including logical, independent
commits; patch sign-offs; and sending patches to a mailing list.
Currently, people who want to cite a particular section tend to either
refer to it by name and let the interested party search through the
document to find it, or link to a given line number on GitHub and hope
the file doesn't change.
Instead, convert the document to AsciiDoc. Build it as part of the
technical documentation, since it is likely of interest to the same
group of people. Provide stable links to the sections which outside
parties are likely to want to link to. Make some minor structural
changes to organize it so that it can be formatted sanely.
Since the makefile needs a .txt extension in order to build with the
rest of the documentation, simply copy the file. Ignore the temporary
file so it doesn't get checked in accidentally, and remove it as part of
the clean process. Do this instead of renaming the file so that people
who have already linked to the documentation (who we're trying to help)
don't find their links broken. Avoid symlinking since Windows will not
like that.
This allows us to render the document as part of the website for the
benefit of others who wish to link to it as well as providing a more
nicely formatted display for our community and potential contributors.

If you have a pcre1 library which is compiled with JIT enabled then
PCRE_STUDY_JIT_COMPILE will be defined whether or not the
NO_LIBPCRE1_JIT configuration is set.
This means that we enable JIT functionality when calling pcre_study
even if NO_LIBPCRE1_JIT has been explicitly set and we just use plain
pcre_exec later.
Fix this by using own macro (GIT_PCRE_STUDY_JIT_COMPILE) which we set to
PCRE_STUDY_JIT_COMPILE only if NO_LIBPCRE1_JIT is not set and define to
0 otherwise, as before.

The test for '--abbrev' in t4201-shortlog.sh assumes that the commits
generated in the test can always be uniquely abbreviated to 5 hex digits
but this is not always the case. If you were unlucky and happened to run
the test at (say) Thu Jun 22 03:04:49 2017 +0000, you would find that
the first commit generated would collide with a tree object created
later in the same test.
This can be simulated in the version of t4201-shortlog.sh prior to this
commit by setting GIT_COMMITTER_DATE and GIT_AUTHOR_DATE to 1498100689
after sourcing test-lib.sh.
Change the test to test --abbrev=35 instead of --abbrev=5 to almost
completely avoid the possibility of a partial collision and add a call
to test_tick in the setup to make the test repeatable (the latter alone
is sufficient to make it robust enough).

fuzzy_matchlines() uses a pointers to the first and last characters of
two lines to keep track while matching them. This makes it impossible
to deal with empty strings. It accesses characters before the start of
empty lines. It can also access characters after the end when checking
for trailing whitespace in the main loop.
Avoid that by using pointers to the first character and the one *after*
the last one. This is well-defined as long as the latter is not
dereferenced. Basically rewrite the function based on that premise; it
becomes much simpler as a result. There is no need to check for
leading whitespace outside of the main loop anymore.

ba1b9cac ("fsmonitor: delay updating state until after split index
is merged", 2017-10-27) resolved the problem of the fsmonitor data
being applied to the non-base index when reading; however, a similar
problem exists when writing the index. Specifically, writing of the
fsmonitor extension happens only after the work to split the index
has been applied -- as such, the information in the index is only
for the non-"base" index, and thus the extension information
contains only partial data.
When saving, compute the ewah bitmap before the index is split, and
store it in the fsmonitor_dirty field, mirroring the behavior that
occurred during reading. fsmonitor_dirty is kept from being leaked by
being freed when the extension data is written -- which always happens
precisely once, no matter the split index configuration.

newest, which was hard to read. Relabel them to B0, B1, B2. Also
illustrate the history after the rebase using the `--fork-point`
facility was made.
The text already mentions use of reflog, but the description is not
clear what benefit we are trying to gain by using reflog. Clarify
that it is to find the commits that were known to be at the tip of
the remote-tracking branch. This in turn necessitates users to know
the ramifications of the underlying assumptions, namely, expiry of
reflog entries will make it impossible to determine which commits
were at the tip of the remote-tracking branches and we fail when in
doubt (instead of giving a random and incorrect result without even
warning). Another limitation is that it won't be useful if you did
not fork from the tip of a remote-tracking branch but from in the
middle.

In several functions, we iterate through a commit list by assigning
`result = result->next`. As a consequence, we lose the original pointer
and eventually leak the list.
Rewrite the loops so that we keep the original pointers, then call
`free_commit_list()`. Various alternatives were considered:
1) Use `UNLEAK(result)` before the loop. Simple change, but not very
pretty. These would definitely be new lows among our usages of UNLEAK.
2) Use `pop_commit()` when looping. Slightly less simple change, but it
feels slightly preferable to first display the list, then free it.
3) As in this patch, but with `UNLEAK()` instead of freeing. We'd still
go through all the trouble of refactoring the loop, and because it's not
super-obvious that we're about to exit, let's just free the lists -- it
probably doesn't affect the runtime much.
In `handle_independent()` we can drop `result` while we're here and
reuse the `revs`-variable instead. That matches several other users of
`reduce_heads()`. The memory-leak that this hides will be addressed in
the next commit.

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.
