Hello,
Hope this is the correct list for this report.
Attached is a script that demonstrates (I think) strange cogito behaviour.
Run it in a temporary directory.
It does the following:
* Create a repository, repo1, add a file to it
* Create a branch inside repo1 and change the file in it
* Switches repo1 to master branch
* Clones repo1 to repo2
* Switches repo1 to alternate branch
* Updates repo2
The odd behaviour is that repo2 changes in the update to show the branch
contents in the working copy. The only actions that has happened in repo1 is
a switch of the working directory to a different branch. It could easily be
that I've misunderstood what switch is doing, but the same operations using
git seem to work as I'd expect (script available if required).
The script then continues with
* Switch repo1 back to master branch
* Update repo2
This time repo2 doesn't change. So I'm more confused :-)
In case you don't want to run the script, sample output follows:

Why has repo2 changed? repo1 had its working copy switched
repo2 shouldn't care about what's in the local copy of repo1.
What exactly is repo2#master tracking? It's certainly not
repo1#master.

Branch already fully merged.

Even more strange, switching repo1 back to "master" and
updating repo2, hasn't changed repo2. The first test showed that
repo2 is not tracking #master; but this test shows that repo2
is not tracking repo1 HEAD either. What is repo2 tracking?
(it seems that it's repo1#branch)
