Remove commas from the end of the macros that define

Remove commas from the end of the macros that define
directives that are used by MPMs.  Previous to this patch,
you would use these macros without commans, which was unlike
any other directives. Now, after the macro, you must have
a comma.  This makes the macros look more like the rest of the
directives.

I know this is cosmetic, and I was going to leave it alone, but when
I found out that it bothered Cliff too, I decided to fix it after all.
