git-completion.bash: replace zsh notation that breaks bash 3.X

When commit d8b45314 began separating the zsh completion from the bash
completion, it introduced a zsh completion "bridge" section into the bash
completion script for zsh users to use until they migrated to the zsh
script.  The zsh '+=()' append-to-array notation prevents bash 3.00.15 on
CentOS 4.x from loading the completion script and breaks test 9902.  We can
easily work around this by using standard Bash array notation.

am: invoke perl's strftime in C locale

We used to convert timestamps in metadata comment of Hg patch to
mbox-looking Date: field using strftime, without making sure the
resulting string is not translated.  Always use C locale for this.

help: include <common-cmds.h> only in one file

This header not only declares but also defines the contents of the
array that holds the list of command names and help text.  Do not
include it in multiple places to waste text space.

t0050: honor CASE_INSENSITIVE_FS in add (with different case)

The test case "add (with different case)" indicates a
known breakage when run on a case insensitive file system.

The test is invalid for case sensitive file system, it will always fail.

Check the precondition CASE_INSENSITIVE_FS before running it.
