This moves "shift" out of the argument processing "case". It also
replaces quite a bit of expr calls with ${parameter#word} constructs,
and uses ${parameter:+word} for avoiding conditionals where possible.

Actually, this is almost the same patch as the one posted during the
1.5.3 semi-freeze. I just checked that it still applies and works,
and that nothing has been changed incompatibly in the mean time.
Some might argue that git-commit.sh could be implemented in C soon,
anyway. Well, exactly that would be an excellent reason to do this
sort of cleanup, since then this file would get moved to
contrib/examples, and of course we want the examples to look as clean
and understandable as possible, don't we?
At more than 4 times as many deletions than insertions, this is a nice
cleanup, and quite more readable.
