Hi,

Recently I was working with ncurses, and when handling the mouse scroll events, I noticed that the curses library does not include the BUTTON5_* macros provided by ncurses. On my system, BUTTON5 corresponds to the mouse down event.

Is there a reason for this, or has it just not been updated? If so, the expectation is that it exists.
