Yes, that is correct.  Previously, the notices on the files were
either "GPLv2 or later", "GPLv3 or later", or
lacking.  There was no GPL2-only code.  The relicensing was based on
the "or later" provision of the previous GPLv2+ terms.  The
license/copyright notices needed to be cleaned up no matter what, and
it made the most sense to simply standardize on GPLv3+.

btw, I listed individual author names on each source file according to
my best recollection, but I most likely missed some.  All contributors
to the project should feel free to add their names to the notices as
appropriate.

Best,

David
