For anyone who hasn't found it, there's a great little utility (on
Linux, at least) called 'rlwrap' which gives you the full readline
feature set on any command line system (like, say, the erlang shell).  I
simply have 'erl' aliased to 'rlwrap -a erl'.  It gives you everything
provided by this patch as well as as a searchable history (just like you
get in bash with Ctrl-r).

(This isn't meant to suggest that the patch isn't worthwhile, just to
note an alternative).

Cheers,

Bernard
