revised EC command

unidirectional pipe with no arguments. with one/two arguments,
the buffer content is piped into the process and replaced with
its output.
 * fixed error handling, now the child's exit status matters
if everything else is OK, as well
 * colon modifier has standard behaviour of returning the command
status
