* src/subshell.c: Reason: in feed_subshell() we are trying to read
	from shell pty,check for retval==-1 && errno != EIO. In that case
	we flame and exit. Otherwise we are trying to write what we've
	read. Good luck doing it if we got errno==EIO, which is _normal_
	for situation when shell just died. Resulting write(1,foo,~0U) is
	somewhat excessively, erm, verbose.
