I think something like what you suggest is fine.  There are many files
out there that have no header, but are distributed together with a
"LICENSE", "COPYING" or "COPYRIGHT" text file that sets forth the terms.
The more you can clarify the license without making it ridiculous, the
better IMO.

This is the FSF's recommended text for code distributed under LGPL.  It
isn't strictly necessary.
