I find myself running 'bzr log -r-10..-1 --lines' quite a lot. Its usually
what I want about 90% of the time.

I think log could be a bit more useful if: 

 * --lines was the default, with the old behaviour coming back with --full

 * A sane default is put in place for bzr log, say -15..-1. .5. If
   somebody really wants more than 15 lines of logs, they can type 
   -r-1..1

Interesting problem trying to figure out how to reliably detect when a
branch becomes diverged in a reasonable manner.
