+### Please describe the problem.
+After branching from master/HEAD^ and deleting the master branch, I was surprised that content introduced in master/HEAD is not reported as unused. Instead, one first has to delete the synced/master branch, and also the remote-tracking branches for master.
+
+Would it make sense to discount synced/* and the remote tracking branches when gathering unused files? If the remote-tracking branch always reflects the state of the remote, tracking a branch should not cause annex to think that the local annex is somehow using all the files on the remote. Or would that be unsafe? As for the synced/* branches I'm not so sure.
+
+### What steps will reproduce the problem?
+Clone annex A to B.
+Branch off of master^ in B.
+Delete master.
+Issue git annex unused. --> Content introduced in master is still not reported as unused.
+Delete synced/master --> Cf. above.
+Delete origin/master and origin/synced/master --> Content is now reported as unused.
+
+### What version of git-annex are you using? On what operating system?
