[CHANGE] Glossary items, punctuation

[Rob Beezer]

If your project does not have a glossary, you can safely skip this.

If it does, then note that the words being explained should be followed by a
period or a semi-colon. PreTeXt is now adding a period for you, as we do with
titles elsewhere. So if you (properly) have punctuation in your source, now you
will get double.

Thus, before your next upgrade, you will want to remove that punctuation from
your source.
