parser does not detect EOF #11

Run this (in *nix):

echo 1 | omega

You will see a never ending output of "prompt> prompt> ...".

Same happens when typing ^D (control-D) into the listener (several times).

Like other filter-like tools, omega should gracefully quit
in this case.

The fix (when done) will assume that the posix module
is available.

revision 50 implements this.

the patch checks whether the input is coming from a pipe
and if so, using the cheap method of interaction, without
readline, checking for ^D and pipe EOF.

Now we get:

prompt> <stdin>: hGetChar: end of file
prompt> <stdin>: hGetChar: end of file
... ad infinitum ...
