This is the stuff I still don't really grok. How do I tell whether it
is GPLv2 or GPLv2+?

This passage [1] contains such a sentence:

"either version 2 of the License, or (at your option) any later version."

Is this not enough? This is what our manual states in regard to GPLv2+:

"GPLv2+: GNU General Public License, version 2 or (at your option) any
later version;"

This is what I used to as a rule.
