And I just noticed that in util.py they are using


instead of


What we know from our Perl stuff is the 'search' behaviour. The 'match' 
matches only from the beginning of a string, so acts like 

In this case they need to add '.*' in front of regexp for globs so this 
gives '^.*rest_of_regexp' where a 'rest_of_regexp' with 'search' would be 
fully sufficient and is probably better in terms of performance.

I'm wondering why 'match' is used here. Maybe Matt can give some insight.
