Removed spaces from before ( in core files

[cflewis]

I've removed the spaces from before ( in the core CVSanalY files. This is the first step towards getting the code PEP-8 compliant. I had to do this by hand, which is why I haven't done extensions yet. I'm tired! :)

This change must be reviewed carefully around regular expressions. All code changes are syntactically equivalent, but if a space is accidentally removed from the regular expression, it's completely broken. As regexes are not unit tested in the code, we have no way of knowing it's been broken.

Please, please, PLEASE check that regular expressions are the same from the old line to the new line. No regex should have been changed (but re.compile (...) is changed to re.compile(...), so shows up in the diff).

When you are completely sure the regexes haven't changed, then do the merge.

Thanks!

Double checked with all regexps, no problem.
Merged and closed.
Thanks for the hard working
