This is not exactly right: if there is a buffer vimgrep makes the search in
the buffer not in the file (written on the disc) which might differ from what
is in the buffer (if it is modified).

You should use vimgrepadd as I poseted (and clear the quickfix list :call
setqflist([])).

You can also use lvimgrepadd and setloclist() instead of vimgrep and
setqflist() and use :llist instead of :clist. This is helpfull if you use
quickfix for compilation errors for example.
