remove gtk_get_option_group
With the flag GTK_DEBUG
, gtk_get_option_group
seems not useful anymore.
Also, I hesitate to remove g_option_context_add_group (ctx, g_irepository_get_option_group ())
, it seems it only appear --help-all
and display all the options from gtk_get_option_group
but I'm not sure if it's only that.
