Hmm. We could easily provide a libreadline port for ports to use, as
long as libedit does everything that's needed for the in-tree users
(are there any others apart from bc and gdb?) The only danger is if
future versions of those grow the need to use other parts of the API
which we don't implement. The upside is that both the FreeBSD and
NetBSD communities would be facing the same problem, meaning greater
developer power to implement new features.
Personally, I think it's worth it to get rid of a GNU dependency in
the base system, as well as reducing the overall amount of functional
code duplication.
