Sorry, I didn't mean to suggest that you should turn on
scroll-conservatively, I just wanted to see what causes recentering.

However, now that I tried your recipe, I see that Emacs 24.3 also
recenters, like the current trunk.  If I then type RET at the "ERC>"
prompt, the display is scrolled so that the last non-empty line is
indeed at the bottom of the window.

I think this is expected, given that scrolltobottom works off the
post-command-hook, no?

Are you sure that Emacs 24.3 behaves differently here?  Did you
perhaps use in Emacs 24.3 erc that is different from the one which was
supplied with the release tarball?
