bug#15323: 24.3; make hideshow use outline-minor-mode-prefix or a similar hs-minor-mode-prefix

[Susanne Oberhauser <froh@suse.com>]

Hi,

hideshow mode has the prefix C-c @ hard coded in it's minor mode map.


C-c @ on a german keyboard actually is  C-c M-q

That makes  C-c @ C-h  into  C-c AltGr-q C-h  which is slow and puts my
fingers at risk :)


Now outline minor mode allows to simply define the minor mode prefix to
something more convenient.


I'd love to have this in hideshow mode, too, e.g. along the lines in the
patch below.

Thanks,


S.
