Comment 7 for bug 1018628

Simplified the test where a simple colo branch creation locks the directory path.

                $ mkdir mywork
                $ cd mywork
                $ bzr init
                Created a standalone tree (format: 2a)
                $ echo A > a && bzr add a && bzr commit -m A
                $ bzr switch -b br1
                $ cd ..
                $ mv mywork mywork1
                $ cd mywork1
                $ bzr branches

This should not give error.
