They can in that case use libedit which exports a libreadline compatibility
interface in the base system (it is working well with the known cisco-like =
UI
things ;) so even in that case I save them space given libedit is required =
for
/bin/sh (the only known problem can happen if the are using unicode and fro=
m my
last test the cisco UI thing is not unicode friendly either so that should =
make
no difference here for them).
The other thing is there are a couple of ABI incompatibilities between the
libreadline version we have in base and newer libreadline which is getting =
more
and more use making it more complicated to manage ports that requires newer
readline.
