Re: [PATCH] - svndumpfilter - add wildcard matchinv

From: Andrei <litvinandrei_at_rogers.com>

Thank you for the feedback. Here is a new version using apr_fnmatch. Based on my tests, it seems to handle escapes ('\') ok and has '[' matching on top of the previous one. I did not see a case which would require me to handle escapes aditionally from apr_fnmatch .. did you
 have any specific functionality in mind that requires this?
