Rewritten git-compat-util.h:skip_prefix() as a loop, so that it doesn't have to
scan through the prefix string twice as a miniproject for GSoC 2014.
(I've just noticed that this miniproject has already been tackled by another
contributor, if that's a problem I can pick something else.)
Looking forward to any kind of feedback.
