What's the flag for the alias-file pipe to msgs under 3.1/2.1?

[Blair P. Houghton]

For some reason, msgs(6) is unsupported in Ultrix.

For no reason, the manual page doesn't list the proper
flag to use when implementing the msgs alias in /usr/lib/aliases.
Looking on other BSD's, one sees

    msgs: "|/usr/ucb/msgs -s"

But the -s is not documented in the section 6 man-page for msgs.

I _could_ just run through all the unused letters of the alphabet,
but something entirely unsettling tells me there may not be
one for this.

Also, would it be illegal to make /usr/msgs a symbolic link to
/usr/local/msgs?
