So woul I.

Personally I often don't want to use pager even for very long output, because
I have very long scrollback on my terminal. That especially makes sense if
the logs were - as I think they should - printed OLDEST FIRST. Than I see the
more recent part immediately and scroll back to the older parts.

I would propose two options:

bzr log -<number>
(for any numerical value of -<number>) would be shortcut for -r -1..-<number>

bzr log -R
(or something else if -R is already taken) would mean to print log reversed.
Ie. oldest to newest for the default case and in combination with the above.
