test-svn-subrepo: fix reference output for svn 1.7 I modified check-code.py "$?" detection because I thought my use was legit, we cannot test exit status of pipelines commands except for the last one without this. So it now tolerates "[$?" which is unlikely to be added by mistake. Tested on: - OSX + svn 1.7.1 - Linux + svn 1.6.12
