I looked into do that, and it's a bit of a pain. Mike's patch is not quite 
right, since it causes update-copyright to generate lines like this:

-   Copyright (C) 2002, 2004-2007, 2009-2017 Free Software Foundation,
-     Inc.

instead of like this:

+   Copyright (C) 2002, 2004-2007, 2009-2017 Free Software Foundation, Inc.

I guess because update-copyright mistakenly counts the continuation indent as 
being part of the previous line when deciding whether to wrap. No doubt this 
could be fixed, but there's a worse problem: the patch affects all files, even 
those shared with Gnulib where it's better to avoid spurious changes. I suppose 
we could start maintaining a list of the dozens of files imported from Gnulib 
and/or elsewhere (currently we do not have such a list) and having 
update-copyright skip files in that list, but this sounds like quite a bit of 
hassle merely to support a preferred style of indentation for copyright notices.
