[BUG] new extension: localbranch

I think I detected a bug in the localbranch:

When I create a repository with some content, then create a test branch, 
change and commit something, switch back to default branch, add a new file 
commit and switch back to the test branch and update to tip, the new file
created in default branch is not being deleted though it should not be there.

What do you think?

Possibly there are similar problems in opposite direction, I didn't check.

Example:

$ mkdir repo
$ cd repo
$ hg init
$ echo "line" > file
$ hg add file
$ hg commit -m 'initial checkin' file
$ hg lbranch
* default
$ hg lbranch test
$ hg lbranch
default
* test
$ echo "line 2" > file
$ hg commit -m "checkin in branch test" file
$ hg log
