   File is generated by vim.
   To regenerate the file,
     1- load the vim function by (or add this to your .vim ?)
        :source vimexpand.vim
     2- call it
        :call VimExpandSimple()
 
 
   It is better than C macro, it gives a cleaner code
   (for error messages, no preproc, doc generation : otherwise no doc string ...)
