A better fix would be for us to add the functionality you're seeking in
readline to libedit.  The latter is really meant to be a complete
replacement for the former.

: I.e. have a PKG_{add-on} variable that controls the default use of an
: add-on dependant for any other package that might use it, and then have
: PKG_{parent-pkg}_{add-on} that can override the default for a given
: dependant in some specific package.  This gets very verbose though.

There is one that might fit this scheme better: libgettext.
