Personally, I would prefer -n1 as default for bzr log. I don't like the
 --short output style, and I'm generally indeed only interested in the
  mainline. I don't think -n0 is very discoverable or obvious though, so it would
 be nice to have a --with-merges option or something like that.

np. it was a nice opportunity to make some more performance improvements
in bzr-svn. 

Unfortunately most of the working tree operations are still a bit too
slow in this tree (graph operations seem fine).
