It's annoying not to be able to put comments and empty lines in the
skipList, when e.g. keeping a big central list of commits to skip in
/etc/gitconfig, which was my motivation for 1362df0d41 ("fetch:
implement fetch.fsck.*", 2018-07-27).
Implement that, and document what version of Git this was changed in,
since this on-disk format can be expected to be used by multiple
versions of git.
