Fix two issues when using post-review with Subversion.

First, using --revision-range with 0 wouldn't work, as the path given
wouldn't have existed in revision 0. The repository path is now assumed
if using revision 0, in order to get a diff of all the files.

Second, sometimes an svn diff would have excess tabs in the diff file headers,
which we wouldn't catch correctly. We now make sure to only split the headers
into two groups, regardless of the number of tabs.
