to not call turn-on-orgstruct++ in my-message-edit-hook

I've observed some bad behavior.
submodule: include magit-blame
theme: cleanup
theme: create status faces
update status submodule
ensure: highlight foreground attribute is reset to nil

Some theme define a very annoying :foreground attribute on the highlight face.
Switching from one theme to another might keep this attribute so reset it in my
theme.
