Okay. So it sounds like there's a "shim" to libedit which would be
the API replacement for libreadline. Could we call that something
cute like 'libreadlinele' ('le' for 'libedit') or 'libeditrl', but
leave libreadline as a separate port?
I'm just wanted to suggest a few alternatives. I am a little uneasy
about just-replacing-libreadline, unless we have something which does
replace all of libreadline. My understanding of this libedit-shim is
that it isn't quite a complete replacement. I think we'd want to be
able to switch a component between "the real" libreadline and this
libedit-shim version. The base system would not include libreadline,
but if someone added it from ports then they wouldn't have to worry
about the real-version changing how the system-components worked.
