Comment 1 for bug 267781

This would certainly be useful when eg wanting to pick up on some work posted to bundle buggy.

As a workaround, you can init a branch and then pull into it.

I investigated adding this, similarly to what's done in cmd_pull. It could be done by copying a little bit of code that checks first whether there's a bundle there, but it might be nice to instead make bundles act more like readonly branches to avoid duplication.
