usr.bin/cmp/misc.c
66	I'm not sure how important it is to be fully compatible, but gcmp prints "byte" instead of "char".
usr.bin/cmp/regular.c
131	Why `%6o`? Isn't 3 enough? Hmm looks like this is what gcmp does.

usr.bin/cmp/misc.c
66	I think here it's better to just maintain internal consistency... I don't /think/ anyone's trying to parse the output.
usr.bin/cmp/regular.c
131	Right, `%6o` to be compatible with gcmp's output, but gcmp also (IIRC) had the first field only 3-wide.

Maintain internal consistency in %b output, as well; %6o back to %3o.
