I always understood it to mean being liberal where the spec was
ambiguous, not to program around other people's bugs when they didn't
read the spec.

For those of us in the e-mail world, SMTP implementations tend to be
very strict because we have observed that badly written spamware has
protocol bugs and real mail software doesn't.  There's a bunch of
highly accurate anti-spam techniques that look for protocol errors.
