I noticed the GNU-ism, too, and wondered about it. It should be fairly
easy to replace with "for n in `ls -a $(dir)`; do rm -fr $n" kind of
thing, but we'd have to filter out '.' and '..' -- which is why find was
used in the first place.
The reason for -print0 is probably in the test suite, where we do have
one or two files with spaces in them; but they really shouldn't show up
in the first level below svn-test-work/, so I guess we can just use
-print and be done with it.
And in case you were wondering why we don't simply nuke the whole
svn-test-work directory: mounting or symlinking a RAM-disk to it is a
rather common setup amongst the developers, in order to make the tests
run faster.
