stupid: handle changes in svn 1.7 diff format Metadata changes are now represented like: Property changes on: a ___________________________________________________________________ Added: svn:executable ## -0,0 +1 ## +* instead of: Property changes on: a ___________________________________________________________________ Added: svn:executable + * Also, I got tired of massaging the diff with regexps, so I extracted the parsing logic in parsediff(). This is no small refactoring but it makes things cleaner and the test suite pass on 1.6 and 1.7 so...
