t1400-update-ref: Add test verifying bug with symrefs in delete_ref()

When deleting a ref through a symref (e.g. using 'git update-ref -d HEAD'
to delete refs/heads/master), we currently fail to remove the packed
version of that ref. This testcase demonstrates the bug.

Fix failure to delete a packed ref through a symref

When deleting a ref through a symref (e.g. using 'git update-ref -d HEAD'
to delete refs/heads/master), we would remove the loose ref, but a packed
version of the same ref would remain, the end result being that instead of
deleting refs/heads/master we would appear to reset it to its state as of
the last repack.

This patch fixes the issue, by making sure we pass the correct ref name
when invoking repack_without_ref() from within delete_ref().

git-submodule: wrap branch option with "<>" in usage strings.

Use "-b <branch>" instead of "-b branch".  This brings the usage
strings in line with other options, e.g. "--reference <repository>".

git p4: RCS expansion should not span newlines

This bug was introduced in cb585a9 (git-p4: keyword
flattening fixes, 2011-10-16).  The newline character
is indeed special, and $File$ expansions should not try
to match across multiple lines.

gitweb.perl: fix %highlight_ext mappings

When commit 592ea41 refactored the list of extensions for
syntax highlighting, it failed to take into account perl's
operator precedence within lists. As a result, we end up
creating a dictionary of one-to-one elements when the intent
was to map mutliple related types to one main type (e.g.,
bash, ksh, zsh, and sh should all map to sh since they share
similar syntax, but we ended up just mapping "bash" to
"bash" and so forth).

This patch adds parentheses to make the mapping as the
original change intended. It also reorganizes the list to
keep mapped extensions together.

compat/fnmatch: fix off-by-one character class's length check

Character class "xdigit" is the only one that hits 6 character limit
defined by CHAR_CLASS_MAX_LENGTH. All other character classes are 5
character long and therefore never caught by this.

This should make xdigit tests in t3070 pass on Windows.

Documentation: improve phrasing in git-push.txt

The current version contains the sentence:

Further suppose that the other person already pushed changes leading to
A back to the original repository you two obtained the original commit
X.

which doesn't parse for me; I've changed it to

Further suppose that the other person already pushed changes leading to
A back to the original repository from which you two obtained the
original commit X.

git-remote-mediawiki: escape ", \, and LF in file names

A mediawiki page can contain, and even start with a " character, we have
to escape it when generating the fast-export stream, as well as \
character. While we're there, also escape newlines, but I don't think we
can get them from MediaWiki pages.

git-fast-import.txt: improve documentation for quoted paths

The documentation mentioned only newlines and double quotes as
characters needing escaping, but the backslash also needs it. Also, the
documentation was not clearly saying that double quotes around the file
name were required (double quotes in the examples could be interpreted as
part of the sentence, not part of the actual string).
