As I tried to say in an earlier mail, this is a binary-incompatible
change, which, AFAICT, we can't introduce without creating a new
version of this structure.

Also, while thinking of this, I'm not sure that this commit-specific
function belongs in the general editor interface. An alternative is
to have svn_ra_get_commit_editor() return a callback/baton that can be
used for this purpose. We should restrict the use of this callback to
either before any editing operations to simplify the implementation.
I admit that this is not entirely unugly either. Better suggestions
welcome.

I'll try to do a complete review of your patch next week apart from
the editor change part. I think you could wait with a next iteration
of the patch until this part of the design is concluded.
Thanks,
//Peter
