How do you remove unneeded patch files?

[Paul Schmehl]

I'm working on a port upgrade.  The existing port has a number of patch 
files in FILESDIR that are no longer needed.  (The changes they made have 
been incorporated into the distro.)  What's the appropriate way to submit 
those changes?  Normally, a send-pr submission will contain the patches for 
existing port files.  There is no patch for these.  They need to be removed.

I could do this:  diff -Naur files/original_patch_file files/empty_file, 
but I don't know if that removes the file or simply replaces it with an 
empty one.
