[PATCH 1/3] maint: document use of copyright ranges

[Eric Blake]

* README: Copy coreutils wording for allowing copyright year
ranges.
* cfg.mk (UPDATE_COPYRIGHT_USE_INTERVALS): Now that GNU Coding
Standards permit it, prefer shorthand copyright.

Happy New Year!  Now that GNU Coding Standards have changed to
permit copyright range abbreviation, and following the lead of
several other projects, I'm using the new year as an opportunity
to take advantage of it.  And my work in previous years to make
copyright updates go smoothly have paid off - I didn't have to
do any manual editing to get various --version outputs to show
the correct 2011!

This patch lays the groundwork, and the next two are all automated.
