Re: [PATCH] rev-list: fix --reverse interaction with --parents

The bad news: I got as far as understanding that the repeated
simplification must be at fault, but gave up on trying to see exactly
_which step_ breaks the output.  Obviously parent rewriting is the
prime suspect.

Yeah, I noticed that running simplify_commit() (hence rewrite_parents())
more than once on the same commit seems to do "unexpected" things, during
my (hitherto unsuccessful) attempt to to make the --simplify-merges
machinery incremental.
