Problem solved.  As one responder pointed out (thanks again Tom),
rearranging the character class [\w\.\-\'] to be [\w\'\.\-] circumvents 
the problem.  This is ostensibly because ' is before . in the ASCII
collating sequence.  Larry, can this be true?  I haven't seen that
documented anywhere, doncha think that's kind of subtle?

Larry Wall said that the problem was due to a bug in the handling of \-
which is fixed in PL 27.  Could that bug be successfully circumvented 
in the fashion described above?
