Yes, indeed.

Newer version of libedit broke this compatibility:

    el_gets -> narrow_read_function
    el_wgets -> wide_read_function

and now they have:

    el_{w,}gets -> wide_read_function

I think that the best way is to put it back (i.e. narrow libedit
functions require a narrow read function), and bump the version of libedit.

Of course that does not help people who have versions of libedit that
broke this compatibility (these define el_rfunc_t in histedit.h).
