Improve join-pane, move-pane and break-pane:

- There is no need for join-pane and move-pane to be different.
- break-pane can just behave like move-window if the source has only one
  pane, instead of failing.
- Add -a to break-pane like move-window.

Also add missing man page bits for previous window-tree.c changes.
