submodule: do not copy unknown update mode from .gitmodules
When submodule.$name.update is given as hint from the upstream in
the .gitmodules file, we used to blindly copy it to .git/config,
unless there already is a value defined for the submodule.
However, there is no reason to expect that the update mode hinted by
the upstream is available in the version of Git the user is using,
and a really custom "!cmd" prepared by an upstream person running on
Linux may not even be available to a user on Windows. It is simply
irresponsible to copy the setting blindly and to attempt to use it
during a later "submodule update" without validating it first.
Just show the suggested value to the diagnostic output, and set the
value to 'none' in the configuration, if it is not one of the ones
that are known to be supported by this version of Git.

git-cherry(1)'s "description" section has never really managed
to explain to me what the command does. It contains too much
explanation of the algorithm instead of simply saying what
goals it achieves, and too much terminology that we otherwise
do not use (fork-point instead of merge-base).
Try a much more concise approach: state what it finds out, why
this is neat, and how the output is formatted, in a few short
paragraphs. In return, provide much longer examples of how it
fits into a "format-patch | am" based workflow, and how it
compares to reading the same from git-log.
Also carefully avoid using "merge" in a context where it does
not mean something that comes from git-merge(1). Instead, say
"apply" in an attempt to further link to patch workflow
concepts.
While there, also omit the language about _which_ upstream
branch we treat as the default. I literally just learned that
we support having several, so let's not confuse new users
here, especially considering that git-config(1) does not
document this.

diff: restrict pathspec limitations to diff b/f case only
builtin_diff_b_f() needs a path, not pathspec. Other modes in diff

Move GUARD_PATHSPEC(), and the "path" assignment statement, which is

Some the labeled list entries have a blank line between the label
and the body text, and some don't. Use the latter style for
consistency; incidentally, syntax highlighting in Vim works better
if there is no blank line there.
Typeset literal options, commands, and path names in monospace.
When using `literal string` mark-up to do so, there is no need to
escape AsciiDoc special characters with backslashes, so make sure we
don't do so.
Replace some double quotes with proper AsciiDoc quotes
(e.g. ``foo'').

State correct usage of literal examples in man pages in the coding standards
The man pages contain inconsistent usage of backticks vs. single quotes
around options, commands, etc. that are in paragraphs. This commit states
that backticks should always be used around literal examples.
This commit states that "--" and friends should not be escaped
(e.g. use `--pretty=oneline` instead of `\--pretty=oneline`).
This commit also states correct usage for typesetting command usage
examples with inline substitutions.

Commit f2e0873 (branch: report invalid tracking branch as gone) removed
an early return from fill_tracking_info() in the path taken when 'git
branch -v' lists a branch in sync with its upstream. This resulted in an
unconditionally added space in front of the subject line:
This reverts commit 5e7dcad771cb873e278a0571b46910d7c32e2f6c; there
may be unbounded number of symbolic refs in the repository, but the
capability header line in the on-wire protocol has a rather low
length limit.
Documentation/git-log.txt: mark-up fix and minor rephasing
- typeset options, commands, and paths in monospace;
- typeset references to sections with emphasis;
- replace some double quotes with proper AsciiDoc quotes (e.g. ``foo'');
- use title case when referring to section headings.

Merge branch 'jc/upload-pack-send-symref' into maint
One long-standing flaw in the pack transfer protocol used by "git
clone" was that there was no way to tell the other end which branch
"HEAD" points at, and the receiving end needed to guess. A new
capability has been defined in the pack protocol to convey this
information so that cloning from a repository with more than one
branches pointing at the same commit where the HEAD is at now
reliably sets the initial branch in the resulting repository.

unpack-trees: fix "read-tree -u --reset A B" with conflicted index
When we call "read-tree --reset -u HEAD ORIG_HEAD", the first thing we
do with the index is to call read_cache_unmerged. Originally that
would read the index, leaving aside any unmerged entries. However, as
of d1a43f2 (reset --hard/read-tree --reset -u: remove unmerged new
paths, 2008-10-15), it actually creates a new cache entry to serve as
a placeholder, so that we later know to update the working tree.
However, we later noticed that the sha1 of that unmerged entry was
just copied from some higher stage, leaving you with random content in
the index. That was fixed by e11d7b5 ("reset --merge": fix unmerged
case, 2009-12-31), which instead puts the null sha1 into the newly
created entry, and sets a CE_CONFLICTED flag. At the same time, it
teaches the unpack-trees machinery to pay attention to this flag, so
that oneway_merge throws away the current value.
However, it did not update the code paths for twoway_merge, which is
where we end up in the two-way read-tree with --reset. We notice that
the HEAD and ORIG_HEAD versions are the same, and say "oh, we can just
reuse the current version". But that's not true. The current version
is bogus.
Notice this case and make sure we do not keep the bogus entry; either
we do not have that path in the tree we are moving to (i.e. remove
it), or we want to have the cache entry we created for the tree we are
moving to (i.e. resolve by explicitly saying the "newtree" version is
what we want).
