9term is a rather good idea which I did not have myself, thank you. :)
rlwrap would probably work too. I'll see what I can do with it...

edit:

Quote:rlwrap: warning: rlwrap appears to do nothing for rc, which asks for
single keypresses all the time. Don't you need --always-readline
and possibly --no-children? (cf. the rlwrap manpage)

Well... :)

edit: Had to use Git for the best option (namely, just use Byron's rc and enable readline (and the built-in history!) myself).


Works. (If readline can't be found, setting LDFLAGS and CPPFLAGS to point to readline's /lib/ and /include/ folders fixes it.)

Finally, a sane shell again. I also used this opportunity to figure out how to make rc case-insensitive when compiled with readline:


Good enough!
