When running "git show-branch" without any parameter in a repository that
has showbranch.default defined, we used to rely on the fact that our
handcrafted option parsing loop never looked at av[0].
The array of default strings had the first real command line argument in
default_arg[0], but the option parser wanted to look at the array starting
at av[1], so we assigned the address of -1th element to av to force the
loop start working from default_arg[0].
This no longer worked since 5734365 (show-branch: migrate to parse-options
API, 2009-05-21), as parse_options_start() saved the incoming &av[0] in
its ctx->out and later in parse_options_end() it did memmove to ctx->out
(with ctx->cpidx == 0), overwriting the memory before default_arg[] array.
I am not sure if this is a bug in parse_options(), or a bug in the caller,
and tonight I do not have enough concentration to figure out which. In
any case, this patch works the issue around.

* maint-1.6.3:
git-clone: add missing comma in --reference documentation
git-cvsserver: no longer use deprecated 'git-subcommand' commands
clone: disconnect transport after fetching
The current code just leaves the transport in whatever state
it was in after performing the fetch. For a non-empty clone
over the git protocol, the transport code already
disconnects at the end of the fetch.
But for an empty clone, we leave the connection hanging, and
eventually close the socket when clone exits. This causes
the remote upload-pack to complain "the remote end hung up
unexpectedly". While this message is harmless to the clone
itself, it is unnecessarily scary for a user to see and may
pollute git-daemon logs.
This patch just explicitly calls disconnect after we are
done with the remote end, which sends a flush packet to
upload-pack and cleanly disconnects, avoiding the error
message.
Other transports are unaffected or slightly improved:
- for a non-empty repo over the git protocol, the second
disconnect is a no-op (since we are no longer connected)
- for "walker" transports (like HTTP or FTP), we actually
free some used memory (which previously just sat until
the clone process exits)
- for "rsync", disconnect is always a no-op anyway

Commit de435ac0 changed the behavior of --decorate from printing the
full ref (e.g., "refs/heads/master") to a shorter, more human-readable
version (e.g., just "master"). While this is nice for human readers,
external tools using the output from "git log" may prefer the full
version.
This patch introduces an extension to --decorate to allow the caller to

* jp/symlink-dirs:
t6035-merge-dir-to-symlink depends on SYMLINKS prerequisite
git-checkout: be careful about untracked symlinks
lstat_cache: guard against full match of length of 'name' parameter
Demonstrate bugs when a directory is replaced with a symlink
When checkout sees that HEAD points to a non-existent ref,
it currently acts as if "-f" was given; this behavior dates
back to 5a03e7f, which enabled checkout from unborn branches
in the shell version of "git-checkout". The reasoning given
is to avoid the code path which tries to merge the tree
contents. When checkout was converted to C, this code
remained intact.
The unfortunate side effect of this strategy is that the
"force" code path will overwrite working tree and index
state that may be precious to the user. Instead of enabling
"force", this patch uses the normal "merge" codepath for an
unborn branch, but substitutes the empty tree for the "old"
commit.
This means that in the absence of an index, any files in the
working tree will be treated as untracked files, and a
checkout which would overwrite them is aborted. Similarly,
any paths in the index will be merged with an empty entry
as the base, meaning that unless the new branch's content is
identical to what's in the index, there will be a conflict
and the checkout will be aborted.
The user is then free to correct the situation or proceed
with "-f" as appropriate.
This patch also removes the "warning: you are on a branch
yet to be born" message. Its function was to warn the user
that we were enabling the "-f" option. Since we are no
longer doing that, there is no reason for the user to care
whether we are switching away from an unborn branch.

Merlyn noticed that Documentation/install-doc-quick.sh no longer correctly
removes old installed documents when the target directory has a leading
path that is a symlink. It turns out that "checkout-index --prefix" was
broken by recent b6986d8 (git-checkout: be careful about untracked
symlinks, 2009-07-29).
I suspect has_symlink_leading_path() could learn the third parameter
(prefix that is allowed to be symlinked directories) to allow us to retire
a similar function has_dirs_only_path().
Another avenue of fixing this I considered was to get rid of base_dir and
base_dir_len from "struct checkout", and instead make "git checkout-index"
when run with --prefix mkdir the leading path and chdir in there. It
might be the best longer term solution to this issue, as the base_dir
feature is used only by that rather obscure codepath as far as I know.
But at least this patch should fix this breakage.

In 0392513 (add-interactive: refactor mode hunk handling, 2009-04-16),
we merged the interaction loops for mode changes and hunk staging.
This was fine at the time, because 0beee4c (git-add--interactive:
remove hunk coalescing, 2008-07-02) removed hunk coalescing.
However, in 7a26e65 (Revert "git-add--interactive: remove hunk
coalescing", 2009-05-16), we resurrected it. Since then, the code
would attempt in vain to merge mode changes with diff hunks,
corrupting both in the process.
We add a check to the coalescing loop to ensure it only looks at diff
hunks, thus skipping mode changes.

When unpack-objects is run under the --strict option, objects that have
pointers to other objects are verified for the reachability at the end, by
calling check_object() on each of them, and letting check_object to walk
the reachable objects from them using fsck_walk() recursively.
The function however misunderstands the semantics of fsck_walk() function
when it makes a call to it, setting itself as the callback. fsck_walk()
expects the callback function to return a non-zero value to signal an
error (negative value causes an immediate abort, positive value is still
an error but allows further checks on sibling objects) and return zero to
signal a success. The function however returned 1 on some non error
cases, and to cover up this mistake, complained only when fsck_walk() did
not detect any error.
To fix this double-bug, make the function return zero on all success
cases, and also check for non-zero return from fsck_walk() for an error.

We traditionally allowed a mbox file or a directory name of a maildir (but
never an individual file inside a maildir) to be given to "git am". Even
though an individual file in a maildir (or more generally, a piece of
RFC2822 e-mail) is not a mbox file, it contains enough information to
create a commit out of it, so there is no reason to reject one. Running
mailsplit on such a file feels stupid, but it does not hurt.
This builds on top of a5a6755 (git-am foreign patch support: introduce
patch_format, 2009-05-27) that introduced mailbox format detection. The
codepath to deal with a mbox requires it to begin with "From " line and
also allows it to begin with "From: ", but a random piece of e-mail can
and often do begin with any valid RFC2822 header lines.
Instead of checking the first line, we extract all the lines up to the
first empty line, and make sure they look like e-mail headers.
A test is added to t4150 to demonstrate this feature.

Instead, let's be more explicit about what we are merging:

in git-merge when we build the simulated FETCH_HEAD output
that we feed to fmt-merge-msg.

If we have both a tag and a branch named "foo", then calling
"git merge foo" will warn about the ambiguous ref, but merge
the tag.
When generating the commit message, though, we simply
checked whether "refs/heads/foo" existed, and if it did,
assumed it was a branch. This led to the statement "Merge
branch 'foo'" in the commit message, which is quite wrong.
Instead, we should use dwim_ref to find the actual ref used,
and describe it appropriately.
In addition to the test in t7608, we must also tweak the
expected output of t4202, which was accidentally triggering

Configuration values are expected to be quoted when they have leading or
trailing whitespace, but inner whitespace should be kept verbatim even if
the value is not quoted. This is already documented in git-config(1), but
the code caused inner whitespace to be collapsed to a single space,
breaking, for example, clones from a path that has two consecutive spaces
in it, as future fetches would only see a single space.

When a branch moves A to B while the other branch created B (or moved C to
B), the code tried to rename one of them to B~something to preserve both
versions, and failed to register temporary resolution for the original
path B at stage#0 during virtual ancestor computation. This left the
index in unmerged state and caused a segfault.
A better solution is to merge these two versions of B's in place and use
the (potentially conflicting) result as the intermediate merge result in
the virtual ancestor.

This test creates two directories, a/b and a/b-2, then replaces a/b with
a symlink to a/b-2, then merges that change into the 'baseline' commit,
which contains an unrelated change.
There are two bugs:
1. 'git checkout' incorrectly deletes work tree file a/b-2/d.
2. 'git merge' incorrectly deletes work tree file a/b-2/d.
The test goes on to create another branch in which a/b-2 is replaced
with a symlink to a/b (i.e., the reverse of what was done the first
time), and merge it into the 'baseline' commit.
