Robert Günzler 4612f9d327 wayland: Allow showing the menu on the focused monitor
This adds an alias 'focused' for selecting the current monitor, which
becomes the default on x11 and wayland. The previous wayland default of
displaying on all outputs moves under '-2' or 'all'.

.Sh DESCRIPTION
.Nm
is a dynamic menu for
.Xr tty 4
.Pq using Xr ncurses 3 ,
X11 and Wayland, inspired by
.Xr dmenu 1 .

When pressing

the selected items are printed to standard output (one per line) and
.Nm
exits.
Entering text will filter the items to those that match the input.
If the number of items exceeds the size of the list,
the items will be paginated.
