ui: edit(): rebase, graft: set HGREVISION environment variable for an editor

rebase and graft commands set 'rebase_source' or 'source' extras for the revision.
Allow an editor to access the extras using HGREVISION environment variable.

This may be useful when an editor is actually a script which modifies a commit
message.

The name 'HGREVISION' has been selected as transplant already sets this variable
for its filters (--filter).

  $ hg init repo
  $ cd repo
  $ cat > .hgeol <<EOF
