Git 1.8.4-rc2

This is with mostly minor documentation and test updates, nothing
spectacular except for removal of funky lstat(2) emulation on Cygwin.

parse-options: fix clang opterror() -Wunused-value warning

a469a1019352b8ef (silence some -Wuninitialized false positives;
2012-12-15) triggered "unused value" warnings when the return value of
opterror() and several other error-related functions was not used.
5ded807f7c0be10e (fix clang -Wunused-value warnings for error functions;
2013-01-16) applied a fix by adding #if !defined(__clang__) in cache.h
and git-compat-util.h, but misspelled it as #if !defined(clang) in
parse-options.h. Fix this.

This mistake went unnoticed because existing callers of opterror()
utilize its return value.  1158826394e162c5 (parse-options: add
OPT_CMDMODE(); 2013-07-30), however, adds a new invocation of opterror()
which ignores the return value, thus triggering the "unused value"
warning.

t/t7407: fix two typos in submodule tests

In t/t7407-submodule-foreach.sh there is a typo in one of the
path names given for a test step.  The correct path is
nested1/nested2/.git, but nested1/nested1/nested2/.git is
given instead.  The typo is hidden because this line also
accidentally omits the && chain operator.  The omitted chain
also means the return values of all the previous commands in
this test are also being ignored.

Fix the path and add the chain operator so the entire test
sequence can be properly validated.

.mailmap: fixup entries

This patch adds no new names, but fixes the mistakes I made in the previous
commits. (94b410bba8, f4f49e225, c07a6bc57, 2013-07-12, .mailmap: Map
email addresses to names).

These mistakes are double white spaces between name and surname,
different capitalization in email address, or just the email address set
as name.

Also I forgot to include James Knight to the mailmap file.

.mailmap: update long-lost friends with multiple defunct addresses

A handful of past contributors are recorded with multiple e-mail
addresses, all of which are undeliverable.  With a lot of help from
Jonathan, we located all of them except for one person, and a pair
of addresses we suspect belong to a single person but we are not
certain.

Update the found ones with their currently preferred address, and
use the last known address to consolidate contributions by the lost
one.

Revert "git stash: avoid data loss when "git stash save" kills a directory"

This reverts commit a73653130edd6a8977106d45a8092c09040f9132, as it
has been reported that "ls-files --killed" is too time-consuming in
a deep directory with too many untracked crufts (e.g. $HOME/.git
tracking only a few files).

We'd need to revisit it later but "ls-files --killed" needs to be
optimized before it happens.
Revert "Add new @ shortcut for HEAD"

This reverts commit cdfd94837b27c220f70f032b596ea993d195488f, as it
does not just apply to "@" (and forms with modifiers like @{u}
applied to it), but also affects e.g. "refs/heads/@/foo", which it
shouldn't.

The basic idea of giving a short-hand might be good, and the topic
can be retried later, but let's revert to avoid affecting existing
use cases for now for the upcoming release.
