New submission from Steve Newcomb <s...@coolheads.com>:

Documentation for the re module insists that matches are made left-to-right 
within the alternatives delimited by an "or* | group.  I seem to have found a 
case where the rightmost alternative is matched unless it (and only it) is 
commented out.  See attached script, which is self-explanatory.
