Hmm, pretty easy to do, and seams to be a resonable idea (more info to
the programmer is good).

ob sh[lr]dl: It seems to me that you (DJ) agree sh[lr]d should not be
overloaded (I hate mul (imul?) for that), but I don't think I've ever
been entirely happy with sh[lr]dl.  It can be used in both 16 and 32 bit
modes (determined by the register, thankfully always present) and I
think the name is slightly confusing with that 'd' in there (is that
what you meant by vague earlier?).  sh[lr]l didn't work for me either. 
If anybody comes up with a good mnemonic (or we decide that overloading
a mnemonic isn't so bad, but I *really* don't like that, assembly can be
confusing), I'll make the change.

Hmmm, what about lshr[lr]?  (just hit me)

Bill
