commit efbe454f0ddc2551741238f2f61a0a2bd67012d4

[mm]: Use less padding in `AL` and `RL`.
* contrib/mm/m.tmac (AL, RL): Reduce "pad" argument to `LB` call from 2
to 1. This keeps marks in `AL` list items from oversetting even when
prefixed (with intra-mark padding), if the enumerator and prefix are
only one character in nroff mode (and similarly thin in troff mode).
`RL` oversets under the same circumstances (because two brackets "["
and "]" are wider than a dot ".") This change however makes the
macros more consistent with each other, and `RL` more consistent with
DWB 3.3 mm, whose manual doesn't document the macros' behavior in this
much detail; I thus regard the alteration as cosmetic.
