This makes using amused a bit nicer on termux where /tmp/ can't be written (or doesn't even exists.) amused still uses /tmp/ if TMPDIR is not specified.

used @openbsd.org initially by mistake and got copied around in most files. Since this has nothing to do officially with the OpenBSD project, use my own email address.

Cm on|off renders the pipe in bold too, use Cm on Ns | Ns Cm off to disambiguate.
