I don't think hacking straight in the wc code will be faster than
using 'svn pg -R .', which gets (and prints) all properties on all
targets in the working copy. It's the C version of what you'll be
writing in perl...
Then, you can catch that output in perl and act on it as required (for
example by changing the file permissions...)

Erik.
