diff -r branch:XXX

Also fetches the revisions.

It seems a bit strange to me. For example, if I do

$ cd /a/project
# Forget that I'm in this project, but I want to see something in
# another project
$ bzr ... -r branch:http://foo.bar

Then, I have completely unrelated revisions in my current directory. I
would have expected operations like "diff" on a remote branch to be
read-only in the current branch, and I'd also have expected to be able
to run them from any directory (currently, I can diff two remote
branch only from a local branch).

This seems to me like a local cache (comparable to GNU Arch's revision
libraries or Bazaar 1's cache ?), and I'm not sure the right place to
store it is the current working directory.

Also, I'd have expected a kind of garbage-collection (or cache
expiry), to keep only the ancestors of the head of the current branch.

Did I miss something, or is it just "on the todo list" ?

Thanks,
