[Xquartz-dev] Re-enable fn for fake mouse buttons

[Martin Otte]

With the last few releases, I could no longer use the fn key on my  
powerbook as a fake mouse modifier.
Here is patch to darwinEvents.c, based on an earlier commit "Re- 
enable support for capslock", that allows fn to be used again for  
fake_button2 or 3:

I prefer to use the fn key for one of the fake clicks because some X  
apps have a use for shift, control, or option clicks.

Thanks,
