Provide a way to communicate additional behaviors and/or appearances
desired from NetHack window port menus.
This is foundation work for changes to follow at a future date.
groundwork only - window port interface change
This changes the last parameter for add_menu() from a boolean
to an unsigned int, to allow additional itemflags in future
beyond just the "preselected" that the original boolean offered.
There shouldn't be any functionality changes with this groundwork-only
change, and if there are it is unintentional and should be reported.
I'll push a formatting guide at some point. There may still be
outstanding changes, but please feel free to resolve those as you arrive
a them.
To the best of my knowledge, there is no changes to the actual code
content, but the formatter does have the occasional bug. If you run into
an issue, please fix it!
