modified fsck.c:fsck_commit(). Replaced memcmp() with starts_with() function.
starts_with() seems much more relevant than memcmp(). It uses one less argument
and its return value makes more sense.
skip_prefix() is not used as it uses strcmp() internally which seems unnecessarily
for current task. The current task can be easily done by providing offsets to the
buffer pointer (the way it is implemented currently).
