[PATCH] SEH: Reimplement the .seh_scope directive

[Julian Waters]

Hi Nick, thanks for chipping in,

Sorry for dragging you into this, it's just that I thought you were the
best person to look to since you authored the .seh_code directive some time
(9 years!!) ago :P

0. I don't mind submitting this under whatever license, so long as I can
contribute it, I'm happy

1. Ah, I thought I could get away with that warning, I didn't know binutils
was compiled with -Werror on. I'll fix it, thanks for the heads up

2. I'm not too sure how to check if there are more than 4, I'll get back to
you on that

3. Where should the documentation be? I know what some (but not all) of the
directives do, so I'll be happy to document the ones I know

4. Ah, the joys of auto formatting. I'll try to get rid of all of them in
the final patch

Thanks for getting back to me, I appreciate the time! :)

best regards,
Julian
