More bugs.

    Plan9 already has "line discipline" modules is several places
    (devcons, 81/2, readln in auth utilities, telnetd), so instead
    of replicating it would be useful to keep it in one place.

i don't have a problem with lines discipline as a technology, it's
just their misuse that concerns me.  i've seen that (in the old system)
readln was duplicated in too many places.  that should be addresed.
adding further /dev/cons modes is a road to ruin:

	they're unnecessary in any modern system -- rob
    
    Raw mode and no echo mode are two different things and lumping
    them together only makes all programs which read passwords
    to be equipped with handling of kill and erase.

on plan9 their are bugger all of these things that want to fool
with the cons mode; the interface is the window system, not some
archaic tty interface.  occassionally you are faced with
this stuff: ftpfs, passwd.  but, for the most part you're not.
