Hi, I've done a microproject, number 15, "Rewrite fsck.c:fsck_commit() to use
starts_with() and/or skip_prefix()." I used only starts_with().
memcmp() returns 0 when both are equal, therefore when replacing with
starts_with() , I used "!" or deleted where appropriate.
I plan to apply for the GSoC 2014. I expect your feedbacks!
