inaccurate commit message message?

The commit message message says "Lines starting with '#' will be
ignored", but fails to say "Lines below this message will be ignored,
even if they don't start with '#'".
If the second sentence is true, I think it (or something equivalent)
should be said, especially because of the relevance during commit
--verbose.

In fact the documentation for commit --verbose explicitly says to note
that the diff lines won't start with '#'s, as if warning people that
those lines might show up in the commit message.
Yet they do not seem to show up... (and I don't think they should)
