Hi Gerco! Thanks for this patch. I've kept meaning to get around to
fixing this, but have been too busy. I gave it a quick skim; I hope
I'll find time for a real review later. (Thanks for including a test
suite as well!)

(For what it's worth, I still think that an API that lets you set
revprops after running through the editor tree would be better, since
you could do signatures and the like, but one could still do that with
a preliminary "dry run" anyway.)

Hmm, are you working against trunk or 1.4? Trunk should have propedit
for URLs since around October.

(As a little note, the indentation in your log message isn't quite our
standard.)

Probably should mention here that propedit_with_revprop is XFail.

Sounds like a TODO worth doing :-)

The indentation on this function seems a little wacky.

... hmm, you've got propset3, so that should be trunk which supports
propedit-URL. Unfortunately I can't test the patch right now; what's
not working about this feature with propedit?

(As an unrelated note, it looks like "svn propedit --revprop -m" fails
to report the "you don't need a log message" error, like with "svn mv
-m" as you separately reported.)

"somewhere else" is vague; might as well be specific.

Sorry for only giving such a superficial review; I hope I'll have time to
actually test out the next version of your patch!
