added C-l to launch subcomposer- in progress
keyboardcomposer will probably launch subcomposer correctly,
but i don't even know if KC blocks or not (untested), and
the SC is certainly a child process of the KC, which is
undesirable. We think that some sort of setpgrp call in
the child may fix that.
