[Python-Dev] IDLE colorizer

A thread on python-ideas is talking about the prefixes of string 
literals, and the regex used in IDLE.

Line 25 of Lib\idlelib\colorizer.py is:

     stringprefix = r"(?i:\br|u|f|fr|rf|b|br|rb)?"

which looks slightly wrong to me.

The \b will apply only to the first choice.

Shouldn't it be more like:

     stringprefix = r"(?:\b(?i:r|u|f|fr|rf|b|br|rb))?"
