Re: [viewvc-users] Bad ra_local URL when repository path is a Windows UNC path

As you likely suspect, the short answer is that ViewVC isn't expecting a UNC
path here, just a local absolute path.  I can't remember right now if
Subversion itself even claims to support UNC paths represented as URLs.  If
it does, then it makes sense to teach ViewVC to handle those cases, too.
