It should have two consequences: (1) When there are many completions,
the *Completions* window might be larger initially.  (2) The
*Completions* window will mostly behave as if ‘temp-buffer-resize-mode’
were enabled by default.  I think the OP's scenario is much more
embarrassing so I think we can live with the consequences of your fix.

Please install it and I'll fix the manual accordingly.

Thanks, martin
