svn: Files added in revision 1 can have wrong added/removed linecounts

If a repository has a path set, files added in revision 1 can have their added/removed lines set correctly.

HTR:

1. Take the repo from FECRU-3452 (https://jira.atlassian.com/secure/attachment/92774/branchtest.zip)
2. Unpack, add to fecru, use path 'our'
3. Index
4. Line count in revision 1 for is wrong:

3.0	2.10

This is caused by svn returning a full path (with us/) when doing

svn diff -r 0:1 file:///home/lukpater/tmp/repos/branchtest/us@1
Index: us/trunk/b
===================================================================
--- us/trunk/b	(revision 0)
+++ us/trunk/b	(revision 1)
@@ -0,0 +1,3 @@
+1
+2
+3

and the path not being found in Svn2InfillProcessor.processDiffPaths() (combined diff path. It seems to work fine when doing a file-by-file diff.
