It was more of a case of 'do we often have to provide this guidance in reviews'? The trailing full stop does appear to come up moderately often, along with other punctuation issues. I am on the 'guidance of the wise and education of others' side of the camp, rather than they being rules and regulations (as was recently misunderstood), so lets educate.

I haven't yet had the time to search deeply, but I'm sure I've also seen various bits of guidance on suitability and style of error messages in the last year of so that the section can be rounded out on that front as well (no doubt similar to some of the commit message guidance).

I would rather hope that we can rely on our contributors to know Git
well enough to ask "git grep" after reading the "follow the style of
existing and surrounding code" rule that governs the overall

I don't see error messages as "code" per se, rather as an attempt at a consistent user interface[*], and the user errors can come from anywhere, so if we have settled on a style, let's say so.
