I agree that having it simple is nice. It just turns out that our fancy
defaults can't be overridden, and have the property that we spend 6/10s
in 'bzr add' of a kernel sized tree checking if the file is ignored.

global user-level ignores solve some of this. (and also handles the
complaint that '.swp' is a user-specific ignored file, and maybe not
everyone should be ignoring it...)

Having a default value for the global user ignore that is used if the
file is not present seems reasonable to me. We can even make it a
trimmed-down version, so it just avoids the worst files (py[co], .o, etc).

One downside is that then adding a single entry to ~/.bazaar/ignore, and
all of them show up again.
We can add a command that makes it easy to populate ~/.bazaar/ignore
with the current default list, and open up EDITOR on that file, so you
can configure it to what you want.

Another possible action is that we can have 'bzr init' drop a default
.bzrignore into the project. Again, this one should probably be a
minimal but sufficient set.

These are not exclusive, we can actually do both. I think we need to
include a default *something* for compatibility with bzr-0.8, but how we
handle new projects needs to be discussed.
