Committing part of a changed file

During elego's SvnDay in Berlin today, the topic of "committing part
of a file" came up (during stefan2's talk about TortoiseSVN (future)
features). As Michael suggested, it would be nice if this could
someday become a feature of core svn.

It just so happens that one of my colleagues (svn user) was bugging me
about the same thing recently. So I did some searching on prior work /
discussion within subversion. Here's an interesting post from way back
(the thread unfortunately died of pretty quickly):

(I'm not volunteering, just putting the information out here in case
someone wants to discuss this ...)
