Nico, Tobias - thanks for the replies, although I wasn't looking for advice exactly :).(*)
I was merely pointing out that the vc-svn.el file in the Subversion repository says specifically for "Emacs 21", and it doesn't work with current Subversion, and thus I thought Subversion (not Emacs) might want to update that contributed file. (Sure, the vc-svn.el in the current Emacs repository of course works with current svn, but equally of course it does not work with Emacs 21. :) I don't doubt there are plenty of other comments in that file that could use updating, but I was just sending the minimal change. To see if anyone cared about fixes to it, for one thing. Best, Karl (*) And sure, I want to upgrade to e24 in principle, but I've been using Emacs for ~30 years and most of my customizations got broken. I'll get through it eventually (or maybe I'll die of old age first :), but anyway, this is irrelevant to the matter at hand.
