I really prefer not to do this "align arguments with opening bracket"
style.  As long as they're indented enough to make them visually distinct
from indentation-for-if-blocks, I find it annoying when functions get
renamed to something with a different length and somebody then wastes
time reindenting all the arguments to match.

I don't particularly object to the main thrust of this patch.  I'm not
sure I like it in huge_mm.h though.  Maybe in mm/internal.h?  I
wouldn't want anyone outside mm/ calling it.
