I meant that with current master it's possible to add these bindings
in the init file because C-TAB and S-TAB they can't be bound by default
in outline-minor-mode to not interfere with major mode key bindings.

In outline-mode (not minor) in current master, TAB is bound to outline-cycle,
and S-TAB is bound to outline-cycle-buffer, but C-TAB is unbound in outline-mode
to not interfere with other uses of C-TAB.

This sounds like a bug.  Please provide a recipe for reproducing it.
