why raw terminal support is broken again. I really do need to
understand input.)
** emacsclient -t from an Emacs term buffer does not work, complains
about face problems. This can even lock up Emacs (if the recursive
frame sets single_kboard). Update: the face problems are caused by
bugs in term.el, not in multi-tty. The lockup is caused by
single_kboard mode, and is not easily solvable. The best thing to
do is to simply refuse to create a tty frame of type `eterm'.
** Maybe standard-display-table should be display-local.

(Fixed, changed emacsclient to check for TERM=eterm. The face
complaints seem to be caused by bugs in term.el; they are not
related to multi-tty.)
