This was a bit convoluted to fix, as none of the hooks erc had could be
used, as they're called while saving too many excursions.  (Well, I
could have rewritten the erc-scroll-to-bottom function to not use
`recenter' at all, which may have been a better idea, come to think of
it.)

But I fixed it a different way, so that now point is kept at the end of
the buffer (if the window is selected).
