Strange.  Modules/readline.c hasn't changed since late October.  More
likely, your platform has downgraded (or it never worked, and you've
never noticed before).

Maybe you should upgrade to a newer version of readline?  There's a
comment for revision 2.49 that seems to imply that you need GNU
readline 2.1 or higher, and that particular change did indeed do
something with the variable rl_completion_append_character.

I suggest upgrading to version 2.2 or 4.2 (both are in common use I
believe; 4.2 is the latests).
