Well, that's a mistake that we should fix.

The Free Software Foundation says:

https://www.gnu.org/licenses/gpl-howto.html

"You should also include a copy of the license itself somewhere in the
distribution of your program. All programs, whether they are released
under the GPL or LGPL, should include the text version of the GPL. In
GNU programs the license is usually in a file called COPYING.

"If you are releasing your program under the LGPL, you should also
include the text version of the LGPL, usually in a file called
COPYING.LESSER. Please note that, since the LGPL is a set of additional
permissions on top of the GPL, it's important to include both licenses
so users have all the materials they need to understand their rights."

That's where I think we've been wrong in the past.  I'll work up a patch.
