When writing programs with "rlfe cat >x.c" instead of "cat >x.c", rlfe
appears to do the wrong thing. I see no output on stdout (not even
echoes of the characters I'm typing). If I then "cat x.c", I can see
the bold interaction as well the lines that should be there.
"rlfe cat" works fine if I don't redirect stdout, and "rlfe foo" works
fine for other programs (e.g. ed).
I guess this use case ("rlfe cat >x.c") is simply unsupported?
