git-diff

I have this very useful function in my .vimrc:

function! MyGitDiff()
  !git cat-file blob HEAD:% > temp/compare.tmp
  diffthis
  belowright vertical new
  edit temp/compare.tmp
  diffthis
endfunction

What it does is basically opening the file I am currently working on from repository in a vertical split window, then compare with it. This is very handy, as I can easily compare changes to the original file.

However, there is a problem. After finishing the compare, I remove the split window by typing :q. This however doesn't remove the buffer from the buffer list and I can still see the compare.tmp file in the buffer list. This is annoying because whenever I make new compare, I get this message:

Warning: File "temp/compare.tmp" has changed since editing started.

Is there anyway to delete the file from buffers as well as closing the vertical split window?
