It cannot do a shallow clone against older servers, no.  I think
it should be able to do a full clone from older servers, but I
need to double check -- at least that is how I meant to write
that thing but it was late night ;-).

I meant to reparse them thear but forgot.  Will remember to fix.

That is why it does not write any temporary files.  It
introduces a way to read graft information from an environment
variable.

This is remnant from my earlier one that did not move MAXPARENT
out from commit-tree I forgot to clean up before calling it a
day.  Will remember to clean up.
