[ snip big explanation; thanks for that! ]
Could you merge the signed and unsigned patterns, using any_fix? Or is
there a reason that cannot work (other than that <su> unsigned_fix seems
buggy, it should say "u")?
Okay for trunk even without that (but please try). Also okay for 7 after
looking for fallout.
Thanks!
