Argh.  The comment at the end of the regex is wrong.  Let me correct that:

###
pattern = re.compile(r"""
           / \*                ##  Leading "/*"

           (                   ##  Followed by any number of
              ([^*])           ##  non star characters
              |                ##  or
              (\* [^/])        ##  star-nonslash
           )*
           \* /                ##  with a trailing "*/"
          """, re.VERBOSE)
###


I'm being too hasty these days... *grin*  My apologies!
