[PATCH] README: Define what a copyright year range means.

[Carlos O'Donell]

GLIBC uses year range notation for copyright years.

There is nothing wrong with using ranges, but
we should adjust the README to mention them.

`6.5 Copyright Notices' says:
~~~
You can use a range (‘2008-2010’) instead of listing individual years (‘2008, 2009, 2010’) if and only if: 1) every year in the range, inclusive, really is a “copyrightable” year that would be listed individually; and 2) you make an explicit statement in a ‘README’ file about this usage.

OK to checkin?

Cheers,
Carlos.
