Thanks!

Is it possible to add a compatibility option which would revert
sh[lr]d to their old meaning?  DJGPP sources are not the only users of
djasm, although that's what djasm was originally invented for.  I
think we should make a good-faith effort not to break
back-compatibility without leaving some escape hatch.

Anyway, this change deserves to be documented, both in the djasm docs
and in wc204.txi.

I wonder why didn't you use "grep -l 'sh[lr]' .../*.asm" here ;-)
