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.
