Ah, so Nick was right.  I had tested multple instructions, but not the
" .... ; .endm" case.

It sure does.

As I explained in my reply to Nick, I have no preference as to what
the fix is.  Jim's first patch looks good to me - eg, it doesn't
require an md hook.  For now, I have a locally patched assembler that
meets my needs.  I'd appreciate it, Jim, if you could eventually apply
your patch.  No hurry, but I'd like to know that this bug will be
fixed sometime so that I can use macros with confidence.

Thanks for your attention,
-Tim
