Yes.

Funny you should mention that... Karl and I were *just* talking about
this issue today. Notice that we just changed svn_handle_error() so
that it would bother to differentiate between a general APR error
vs. a SVN-specific error. But the APR-error section has its own
apr_strerror() routine. Perhaps we should imitate with our own
svn_strerror()... just look up the svn errorcode in a static array of
strings.
