If a branch name is longer than four characters then memcmp() reads over
the end of the static string "HEAD". This causes the following test
failures with AddressSanitizer:
And if a branch is named "H", "HE", or "HEA" then the current if clause
erroneously considers it as matching "HEAD" because it only compares
up to the end of the branch name.
Fix that by doing the comparison using strcmp() and only after the
branch name is extracted. This way neither too less nor too many
characters are checked. While at it call strchrnul() to find the end
of the branch name instead of open-coding it.

bash prompt: indicate dirty index even on orphan branches
__git_ps1() doesn't indicate dirty index while on an orphan branch.
To check the dirtiness of the index, __git_ps1() runs 'git diff-index
--cached ... HEAD', which doesn't work on an orphan branch,
because HEAD doesn't point to a valid commit.
Run 'git diff ... --cached' instead, as it does the right thing both
on valid and invalid HEAD, i.e. compares the index to the existing
HEAD in the former case and to the empty tree in the latter. This
fixes the two failing tests added in the first commit of this series.

sha1: provide another level of indirection for the SHA-1 functions
The git source uses git_SHA1_Update() and friends to call into the
code that computes the hashes. Traditionally, we used to map these
directly to underlying implementation of the SHA-1 hash (e.g.
SHA1_Update() from OpenSSL or blk_SHA1_Update() from block-sha1/).
This arrangement however makes it hard to tweak behaviour of the
underlying implementation without fully replacing. If we want to
introduce a tweaked_SHA1_Update() wrapper to implement the "Update"
in a slightly different way, for example, the implementation of the
wrapper still would want to call into the underlying implementation,
but tweaked_SHA1_Update() cannot call git_SHA1_Update() to get to
the underlying implementation (often but not always SHA1_Update()).
Add another level of indirection that maps platform_SHA1_Update()
and friends to their underlying implementations, and by default make
git_SHA1_Update() and friends map to platform_SHA1_* functions.
Doing it this way will later allow us to map git_SHA1_Update() to
tweaked_SHA1_Update(), and the latter can use platform_SHA1_Update()
in its implementation.

The caller is preparing a narrowed-down copy of the working tree and
this function is asked if the path should be included in that copy.
If we say yes, the path from the working tree will be either symlinked
or copied into the narrowed-down copy.
For any path that is a symbolic link, the caller later fixes up the
narrowed-down copy by unlinking the path and replacing it with a
regular file it writes out that mimics the way how "git diff"
compares symbolic links.
Let's answer "no, you do not want to copy/symlink the working tree
file" for all symbolic links from this function, as we know the
result will not be used because it will be overwritten anyway.
Incidentally, this also stops the function from feeding a symbolic
link in the working tree to hash-object, which is a wrong thing to
do to begin with. The link may be pointing at a directory, or worse
may be dangling (both would be noticed as an error). Even if the
link points at a regular file, hashing the contents of a file that
is pointed at by the link is not correct (Git hashes the contents of
the link itself, not the pointee).

Git-merge-file is documented to return one of three exit
codes:
- zero means the merge was successful
- a negative number means an error occurred
- a positive number indicates the number of conflicts
Unfortunately, this all gets stuffed into an 8-bit return
code. Which means that if you have 256 conflicts, this wraps
to zero, and the merge appears to succeed (and commits a
blob full of conflict-marker cruft!).
This patch clamps the return value to a maximum of 127,
which we should be able to safely represent everywhere. This
also leaves 128-255 for other values. Shells (and some parts
of git) will typically represent signal death as 128 plus
the signal number. And negative values are typically coerced
to an 8-bit unsigned value (so "return -1" ends up as 255).
Technically negative returns have the same problem (e.g.,
"-256" wraps back to 0), but this is not a problem in
practice, as the only negative value we use is "-1".

add_submodule_odb: initialize alt_odb list earlier
The add_submodule_odb function tries to add a submodule's
object store as an "alternate". It needs the existing list
to be initialized (from the objects/info/alternates file)
for two reasons:
1. We look for duplicates with the existing alternate
stores, but obviously this doesn't work if we haven't
loaded any yet.
2. We link our new entry into the list by prepending it to
alt_odb_list. But we do _not_ modify alt_odb_tail.
This variable starts as NULL, and is a signal to the
alt_odb code that the list has not yet been
initialized.
We then call read_info_alternates on the submodule (to
recursively load its alternates), which will try to
append to that tail, assuming it has been initialized.
This causes us to segfault if it is NULL.
This rarely comes up in practice, because we will have
initialized the alt_odb any time we do an object lookup. So
you can trigger this only when:
- you try to access a submodule (e.g., a diff with
diff.submodule=log)
- the access happens before any other object has been
accessed (e.g., because the diff is between the working
tree and the index)
- the submodule contains an alternates file (so we try to
add an entry to the NULL alt_odb_tail)
To fix this, we just need to call prepare_alt_odb at the
start of the function (and if we have already initialized,
it is a noop).
Note that we can remove the prepare_alt_odb call from the
end. It is guaranteed to be a noop, since we will have
called it earlier.

If one side deletes a file and the other changes its
content, we notice and report a conflict. However, if
instead of changing the content, we change only the mode,
the merge does not notice (and the mode change is silently
dropped).
The trivial index merge notices the problem and correctly
leaves the conflict in the index, but both merge-recursive
and merge-one-file will silently resolve this in favor of
the deletion. In many cases that is a sane resolution, but
we should be punting to the user whenever there is any

any pathspec mean "everything in the working tree" (before 2.0, they

the end user did not give us any pathspec. At 2.0, we updated the

top-level, by using a pathspec magic "top".
The call to parse_pathspec() using the command line arguments is,
however, made with PATHSPEC_PREFER_FULL option since 5a76aff1 (add:
convert to use parse_pathspec, 2013-07-14), which predates Git 2.0.
In retrospect, there was no need to turn "adding . to limit to the
directory" into "adding :/ to unlimit to everywhere" in Git 2.0;
instead we could just have done "if there is no pathspec on the
command line, just let it be". The parse_pathspec() then would give
us a pathspec that matches everything and all is well.
Incidentally such a simplification also fixes a corner case bug that
stems from the fact that ":/" does not necessarily mean any magic.
A user would say "git --literal-pathspecs add -u :/" from the
command line when she has a directory ':' and wants to add
everything in it (and she knows that her :/ will be taken as
'everything under the sun' magic pathspec unless she disables the
magic with --literal-pathspecs). The internal use of ':/' would
behave the same way as such an explicitly given ":/" when run with
"--literal-pathspecs", and will not add everything under the sun as
the code originally intended.
Documentation: AsciiDoc spells em-dash as double-dashes, not triple
Again, we do not usually process release notes with AsciiDoc, but it
is better to be consistent.
This incidentally reveals breakages left by an ancient 5e00439f
(Documentation: build html for all files in technical and howto,
2012-10-23). The index-format documentation was originally written
to be read as straight text without formatting and when the commit
forced everything in Documentation/ to go through AsciiDoc, it did
not do any adjustment--hence the double-dashes will be seen in the
resulting text that is rendered as preformatted fixed-width without
converted into em-dashes.
