Generally this seems very nice. Thanks for all the good work.

Since I have been working on native plugins (rather than spawning
sub-processes) I figured I would give it a shot.
The attached patch modifies your code so that acts like a real bzr plugin.

This should work with the latest bzr, but should also be compatible with
my work on updating the plugin system.
If you have a stock bzr, then you want put shelf into BZRPLUGINPATH=
(It technically loads all of the .py files, but it only gets commands
out of the last one).
If you have applied my last patch, you could just put the directory into
~/.bzr/plugins/
And since I use the "__init__.py" form, it should load automatically
(and only load __init__.py until you need more.)

Anyway, it seemed nicer to use bzrlib rather than spawning bzr for
different interactions. Though I still cheat a little bit by passing a
StringIO() object as the "output file" of some commands. Instead, it
would make more sense to tie in at a lower level, rather than at the
show_diff_trees() level.
