This patch is actually a xresources patch for dwm, applied to dmenu.
The patch add the ability to configure dmenu via Xresources by using arbitrary resources, not specific ones. Xresources values override default settings and can be overriden by command line arguments.
All thanks should go to the authors of xresources patch for dwm, xresources and xrdb patches for st.
