[patch] Some improvements for m68k/mri mode

This part of your patch breaks the gasp MRI macro test in the gas
testsuite.  Since I am not familiar with MRI I do not know if the test
or the patch is broken.  Please can you have a look at this and
resubmit your patch either with a corrected test or a fixed change to
macro.c.

Cheers
