Re: [PATCH] git-compat-util.h:rewrite skip_prefix() as loop

To my surprise, git format-patch had removed the Git Notes that I had
put to my commit (regarding GSoC). I have written this patch as a part
of the GSoC 2014 MicroProject for Git. Going through the mail-chain I
observed that many students have attempted this Microproject. So is it
ok if I stick to this Microproject or should I go with another one?
