Re: libguile and readline

I think I have a possible sollution for this.

IIRC, libguile links in libreadline because the REPL uses
readline, right?

But IMHO, any application which uses the REPL is enought based
on Guile (not _lib_guile!) to make it in our interest to
"infect" it with the GPL (did anyone realize that with a few
lines of code I could produce a "myguile" interpreter, in all
ways identical to Guile but with some proprietary license?
Except for the fact that readline gets linked too, of course).

And of course, most applications will _not_ use the REPL (those
that want Guile as an extension language), so it also configures
unnecessary bloat.

I think the sollution here is to rip the REPL (and anything that
uses readline) off from libguile into a new (GPLed) library -
say, libguile-repl. Then guile-config may gain an argument
"--with-repl"; with this argument, it links libguile-repl and
libreadline, without it it doesn't.

We get the desired effect; applications wishing to use Guile as
an extension language don't have to be GPLed, but modified Guile
interpreters do.

Of course this _could_ break existing software, but this is what
sonames are for :-)
