put a line of vim rc on head of .[ch] files

Hi.

all the .[ch]s of libgdome has a line of emacs-specific rc line of style.
for the vim users, I ask to put another line of rc.

e.g.
/* -*- Mode: C; indent-tabs-mode: t; c-basic-offset: 8; tab-width: 8 -*- */
/* vi:set syntax=c cindent expandtab tabstop=8 softtabstop=8 shiftwidth=2: */

I don't know what options of vim exactly equivalent to emacs ones.

this issue may solve the space-tab-mixed indentation of this moment.

thx.
