[dev] [PATCH] dmenu: Add commandline-options to determine Xinerama-screen

Moin,

if no -m option is given to dmenu, it infers it's xinerama-screen from
the mouse-position. On heavily keyboard-driven window-managers, the
mouse-position differs heavily from where the attention is sometimes (I
personally hate mouse-follows-focus, so when I change the focus via
keyboard to another screen, the pointer remains at it's position), thus
creating a somewhat unsetting experience, when dmenu suddenly appears on
the „wrong“ screen.
With the attached patch, -m can (additionaly to taking a number) also
takes „focus“ and „mouse“ as options. The latter represents the current
default behaviour, the former uses the center of the window which
currently has the input-focus to determine the screen.

Greetings,

Mero
