One minor difference is that fsck wants an unabbreviated SHA-1, using
parse_oid_hex() instead of get_oid_committish(). Would you be OK with
also changing fsck to take a committish instead of a full SHA-1?
Is there a good place for the common helper? Since it's an oidset, I
could put it in oidset.c. oidset_parse_file() or something.

Is there a good spot for the generic skipList documentation? The only
common text would be:
... comments ('#'), empty lines, and any leading and trailing
whitespace is ignored
