I've set "Autoclose only" to "master".
* When I push a commit with `Fixes T6` to master, it creates a link to the commit and closes the task. When I push a similar commit to another branch it doesn't close the task, but it also doesn't create a link to the commit.
* When I push a commit with `Refs T6` to master, it creates a link to the commit in the task. When I push a similar commit to another branch it doesn't link to the commit.
