bug in rmail

[utzoo!decvax!ucbvax!mhtsa!ihnss!cbosg!cbosgd!mark]

The 4bsd rmail program contains a bug which will cause it to choke
with a usage message if you try to rmail to two or more people.
This doesn't usually show up, but if you batch the mail (as the new
sendmail program does) it will screw up.  The fix is easy, and I urge
all 4bsd sites to fix it.  Only the usage check is wrong, the code can
handle it properly.  At the beginning of main, change
	if (argc != 2) {
to
	if (argc < 2) {

	Mark
