Anil's point was that many Unix utilities use different flavours of
regular expressions.  I for one find that to be a nuisance too.  Why
should grep use different syntax for its regular expressions than ex?
(I know they're quite similar, but at least on our system, they're not
identical as far as I can make out from the man pages.  Luckily, I've
only run into the subtleties once or twice.)
