Ups, sorry about that. There were some commits to that folder in the
mean time, so it doesn't crash anymore with this merge command.

Try this instead:
$ svn merge -r24000:23999
http://tortoisesvn.googlecode.com/svn/trunk/contrib/diff-scripts/diff-xls.js
diff-xls.js

seems you have to reverse-merge the latest revision.
