I wouldn't mind having a situation like this, though...

login:  explorer -ppp
Password: 

Starting PPP session...

The stuff AFTER the user id is put into LOGIN_ARGS, and that is the ONLY
variable that can be munged at login.

That's safe enough I think, and would allow a limited form of what the
user is asking for.

I, too, saw this pr and got rather worried.
