This could be nicely resolved by renaming the arguments "a" and "b", and having the diff display "a, b". It's quite natural (both the diff ordering and the arguments ordering), and they are consistent with each other. So 'a' stands for 'after' and 'b' for 'before', right? :-)

difflib uses 'a' and 'b' for before and after (orig,new in svn terms, with edits/diffs from a to b) respectively. Not really great. The docs then have to explain what 'a' and 'b' are and the implications for interpreting the output.
