A lot of shell scripts contained stuff starting with
while case "$#" in 0) break ;; esac
and similar. I consider breaking out of the condition instead of the
body od the loop ugly, and the implied "true" value of the
non-matching case is not really obvious to humans at first glance. It
happens not to be obvious to some BSD shells, either, but that's
because they are not POSIX-compliant. In most cases, this has been
replaced by a straight condition using "test". "case" has the
advantage of being faster than "test" on vintage shells where "test"
is not a builtin. Since none of them is likely to run the git
scripts, anyway, the added readability should be worth the change.
A few loops have had their termination condition expressed
differently.

Make git-mergetool prefer meld under GNOME, and kdiff3 under KDE. When
considering emerge and vimdiff, check $VISUAL and $EDITOR to see which the
user might prefer.

This fixes complaints from Junio for how messages and prompts are
printed when resolving symlink and deleted file merges.

Create common function check_unchanged(), save_backup() and
remove_backup().
Also fix some minor whitespace issues while we're at it.

If the file we are trying to merge resolve is in git-ls-files -u, then
skip the file existence test. If the file isn't reported in
git-ls-files, then check to see if the file exists or not to give an
appropriate error message.

The git-mergetool program can be used to automatically run an appropriate
merge resolution program to resolve merge conflicts. It will automatically
run one of kdiff3, tkdiff, meld, xxdiff, or emacs emerge programs.
