How about just doing it *after* the commit completed? That is, inside
commit_body() after 'current' has been incremented?

There's a very small window where clients will see them, but all they'll
see is an unrecognized property in the svn:* namespace, so they're
supposed to ignore it. The overall effect won't be much different from
that stray "is-fresh-txn-root: y" on committed noderevs.

(I'm not sure it's a good idea, but it definitely is robust against
power-downs, so I'm putting it on the table anyway.)
