How to remove 2 or more empty lines when closing the the file?

[Eric Leenman]

Hi,

With the follwing subtitue it's possible to remove blocks of 3 empty lines
:%s/^\n\{3}//

How do you need to change it, so that it does remove blocks of 2, or more, 
empty lines?

And how do you give this command just before closing the file?

Rgds,
Eric

I'm using this to remove trailing spaces:

 Remove trailing spaces when saving text files
 See :help restore-position
function! RemoveTrailingSpaces()
   exe normal msHmtgg
   %s/\s\+$//ge
   exe normal 'tzt`s
endfunction

au BufWrite * if ! bin | call RemoveTrailingSpaces() | endif

The function restores cursor position and does not give any warning
because of the 'e' flag. You can do the same things for empty lines.
