The Beirc in CVS behaves incorrectly wrt. its "input-memory" feature
when changing tabs - it inserts the memorised input every time the
editing stream rescans, which worked by accident in Goatee, because
Goatee silently ignored any calls to `replace-input' during a rescan
(which is not correct). Drei is more strict, and this patch is
necessary to make Beirc work properly again.
