-display patch for xwinclip

[Harold L Hunt II]

Jeremy,

Excellent work!

We need more people like you that just dive in and write a feature when 
they want it, even if they have some hurdles to jump, such as learning 
how to program in C and use diff.  I think you did a spectacular job.

I will commit the patch and release a new version of xwinclip when I get 
a chance.
