*	spawned pseudoterminal (on #run) is not checked for echo on/off

*	undocumented feature: ~-1~ -- document it? remove at all? change?

*	--More-- kludge -- do it in a non-kludgy way

*	need a README

*	{#var color ~7~;#var color} shows {} -- it shouldn't get interpreted

*	TELNET negotiations of echo can break either Genesis and Arkadia
	MUDs when done one way, or real telnet servers when done the other
	one.  Hrm.

*	tintin's messages should use ~7~, not the previous colour,
        while still preserving whatever the colour was

*	no bidi support
