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.

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.
