I noticed how hard dealing with dmenu's patches was, so I gave it a try making them easy to manage. For example, this simple lines will take care of the border patch for you:

==========================================================

# path/to/dmenu

./handle patch border # Apply patch, quietly by default

./handle depatch border -d # Remove patch, showing compiler output (debug)

==========================================================

Currently 31/32 official patches are available. You can find out more on the repo (https://github.com/jaimecgomezz/dmenu). Of course, your contributions or own patches are welcomed!

Hope you can find it useful!
