As the original "../parse" file will have mixture of revs (i.e. the
object names) and whatever rev-list options (e.g. "--date-order")
you gave from the command line, here is a band-aid to sift them into
two, to be applied on top of 3361a548 (Allow git-filter-branch to
process large repositories with lots of branches., 2013-09-10).
I wish there was a way to tell rev-parse "give us only flags
relevant to rev-list, don't include revs in the output", but I do
not think there was ever any such option (we can get revs without
any flags with --no-flags, though).
