Exclude masks (or include masks):
- *\*svn\*\* - Exclude all subdirectories and files in them below any directory with a suffix of svn
- *\*svn\* - Exclude any files in directories with svn as a suffix
- *\*svn - Exclude empty directories with svn as its suffix
- Note that slash direction is important
- If empty directory pruning is enabled, two masks are required: *\*svn\*\* and *\*svn\*
- Otherwise three masks are required: *\*svn\*\* and *\*svn\* and *\*svn
