Mention the behavior if user selects CONFIG_SH_IS_ASH but not
CONFIG_ASH. We will be explicit that invocations like "busybox ash"
will not work for such configuration.
Also clarify help text of CONFIG_BASH_IS_* that bash compatibility in
ash is not complete. (It shouldn't be anyway - ash can't support every
bash quirk out there.)

The same can be done for msh, but we are probably better off just deleting it
in a next versio or two.

On user request.
I thought enabling/disabling them all together is more consistent.
Evidently, some people do want them to be separately selectable.
