No, it does not.  This is also a concern for the Python 2 -> Python 3 merging,
where (I think) we decided not to have shared history.  Transplant already
does most of the job (including recording the source hash of transplanted
changesets), but it lacks blocking and consistent rejection of already-merged
changesets (it does not read the source hashes it records, but keeps a local
cache of such hashes instead, which obviously doesn't do anything across
repositories.)  I think it should be possible to have transplant regenerate
and update that cache automatically on clone/pull/etc.

I guess this is a relatively simple task for a Mercurial hacker, and if it's
decided to use this workflow "someone" ;) could address it at the PyCon sprint.

two, excepting that thou then proceed to four. Tabs are right out.
