usage.c: don't copy/paste the same comment three times

Browse Source 
In ee4512ed48 (trace2: create new combined trace facility,
2019-02-22) we started with two copies of this comment,
0ee10fd129 (usage: add trace2 entry upon warning(), 2020-11-23) added
a third. Let's instead add an earlier comment that applies to all
these mostly-the-same functions.
