[PATCH] More typeset -p troubles

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxx>]

The "-m pattern" option is supposed to enable printing namespaces, but
that didn't work when combined with -p.

The -p option could also cause an unset parameter to become set if a
named reference pointed at it.

Noticed but NOT fixed here:  The "-p 1" option (add newlines within
array assignment output) does not work when combined with "-m".
