[development] svn 1.5 supports -p

Hello world, The first public release candidate of subversion 1.5.0 (RC4) is out there. There are several good things there but * 'svn diff -x' now takes '-p' extension option (issue #2995) cures a long standing nuisance for us. Thanks to the subversion team for adding this feature. Regards Karoly Negyesi
