Your 'aliases' also seem to affect the same things that Aaron's defaults
affect. They at least are trying to solve the same problem. So I would
like to understand the differences. And have a discussion about the
tradeoffs.

I don't think we want to have both defaults and aliases. Since otherwise
scripting interfaces would need something like 'bzr --no-aliases
--no-defaults status'.

I think we might want a bigger knob or perhaps just expand --builtins to
disable all non-default behavior. I'm not sure if it should disable
plugins (right now the thought is that plugins can provide extra
transports, so while we don't want to use overwritten commands, we do
want to use the extra transports).

Anyway, the idea of aliases is nice, and it seems a little bit more
flexible than defaults. Though do you allow overriding a command with an
alias?

log = log -r -10..-1
