This is a tty interface problem, which surfaces from time to time
with programs like g.help that change the keyboard interface from
normal mode to single-character mode (possibly noecho as well). If
these programs don't exit properly, the keyboard interface is not reset.

In particular the normal Unix mode of operation is to convert the
RETURN key (ctl-M) to a LINEFEED (ctl-J). If you are seeing RETURN
not working but LINEFEED working, then you are seeing the effect
of the program not restting the interface back to its normal state

Depending on you system, you can reset the interface to a "normal" state
with the stty command, or the reset command, or the tput command:
	stty sane
	reset
	tput init

Of course you would have to type LINEFEED (ctl-J) instead of RETURN
	(ctl-J) stty sane (ctl-J)

Hopefully, this problem has been solved in 4.1. There maybe an update
on moon for g.help.
