Thanks,  I thought I had fixed that at some point.

However, your suggestion does not quite work either because I'm doing  
the matching inside a re.findall  where I've read the entire file into  
a single string.  In that case the only instance of ^ is at the very  
beginning of the file.  So substituting \n for ^ in your suggestion  
works.  I've also got to make the [^%]* non greedy.   I think you may  
also have been working with a slightly out of date version of texMate  
since I had just recently modified this regular expression to  
correctly detect \usepackage{x,y}  and the , was missing in the third  
capture group.  Here's what I ended up with that appears to work.   
I'll commit this today sometime.

r'(\n[^%]*?)\\usepackage(\[[\w, \-]+\])?\{([\w,\-]+)\}'
