Hmm, I thought I had done the experiment and found differently. But
redoing it, I see that you are indeed right.

Yeah, but there is a risk of getting confused while bisecting looking
for the revision that introduced a certain bug.

In emacs-bzr-get-version, in version.el, there seems to be a special
branch in the cond dealing with lightweight checkouts. Maybe you could
just remove that branch? It will only work, and unreliably to boot,
with a lightweight checkout from a local branch.

I can live with that, if you don't think my suggestion above is good.
