Commented Issue: Error message "Invalid output from SVN tool" is too broad [11742]

There are a number of places in the Svn.cs code that just emit "Invalid output from SVN tool". We have intermittent build failures with TeamCity. More informative error messages would help in tracking these down.

I've made a patch in Subversion patch format - submitted over at patches.
