Subject: [PATCH] mhmail: Don't invoke inc when called without arguments. We
 can't provide a full mailx-replacement anyways. By
 magically invoking inc(1), we likely confuse the user.
 Instead tell him that he can invoke inc(1) himself. This
 doesn't mess with the important property: mhmail is a mailx
 replacement for scripts to send mail.
