git-svn: Always duplicate paths returned from get_log
git-svn: Always duplicate paths returned from get_log

This makes get_log more safe to use because callers cannot run into path
clobbering any more. The additional overhead will not affect performance
since the critical calls from the fetch loop need the path duplication
anyway and the rest of the call sites is not performance critical.
