I see one problem with this approach.
The PREV revision might not be related to the path your working
copy came from. Especially if you have multiple projects sharing
a repository, -c PREV will often result in an empty diff for the
given working copy.
-c COMMITTED would always generate a diff, but PREV is just COMMITTED-1
so it might not always be what you are looking for. You're really
looking for something that shows the most recent *operative* revision
for the working copy older than COMMITTED. But this isn't currently
available as a keyword.

Regardless, note that with a 1.7 svn client you can use this workaround
to run the equivalent of diff -c PREV: svn log -r PREV --diff --limit 1
