How to ‘custom install’ with brew

So I have to edit the install of wine, and apply a custom patch. The patch I want is here…

https://bugs.winehq.org/attachment.cgi?id=38156

and when I add these lines with brew edit wine

patch do
  url "https://bugs.winehq.org/attachment.cgi?id=38156"
  sha256 "f1c4537f38e258c810ca33455e0947e3b2be1087bf9445fadac00424f294c004"
end

and then try to install, it does not actually add the patch. It seems to be downloading it from a prepackaged and compiled source because this is the terminal output…

==> Caveats
You may want to get winetricks:
  brew install winetricks

 By default Wine uses a native Mac driver. To switch to the X11 driver, use
regedit to set the "graphics" key under "HKCUSoftwareWineDrivers" to
"x11" (or use winetricks).

For best results with X11, install the latest version of XQuartz:

and not downloading from where it says to in the brew edit wine file…
