Change in ispell's copyright -> nonfree?
Upstream ispell 3.2.x has made the following change in its copyright
(compared to 3.1.20, which we currently distribute).
This sounds nonfree to me; am I wrong? If he were to change that
"must" to a "should," would it then be DFSG-compliant? If not, what
changes would you suggest?
Thanks.
