ui: edit(): transplant: set HGREVISION environment variable for an editor
transplant command set 'transplant_source' extra for the revision.
Allow an editor to access the extra using HGREVISION environment variable.
This may be useful when an editor is actually a script which modifies a commit
message. Transplant filters is an alternative way to do it.
