Support for SVN repository on a UNC path on Windows

[morphiend@…]

While setting up a Trac installation a year ago, I ran into a problem where my SVN repository was stored on a UNC accessible path on a Windows-based Apache system. In other words, I was running Trac on Apache for Windows, with the python module for Apache. Our SVN repository was stored on a separate network drive and only accessible via a UNC path.

At the time I was using Trac 0.11.x (not sure of the revision, and I no longer operate that system).

The problem is due to SubversionRepository _init_'s not handling the UNC slashes properly. When the path is fixed by converting the '\'\' to '\' the UNC slashes were being transformed to just '\' instead of staying '\'\'. I corrected this by adding splitunc() call before the replace and only performing the replace on the non-UNC portion of the path.

I've attached a diff patch making the similar change to the latest version from the 0.12 trunk, as well as the original modified version from my 0.11 installation.
