I think I have to say no to this one. People might be using aliases to
avoid/get paging today so this is a clear BC breakage... and offers
nothing users can't do for themselves in their config file (which
they're already editing), possibly by adding --pager. 

It's also possible with aliases to create things (for instance with
revsets and templates) that are radically different in usage than the
commands they alias, so that they will be thought of as new commands
rather than simply tweaked commands.

To Durham's complaint that there's no easy way to append to global
attend settings, I think the right fix is to add a new more granular
setting, perhaps:

[pager]
attend-fancylog = True
attend-export = False
