[LU-17328] don't allow non-ASCII characters in commit messages

Description

Some Git commit messages have control characters, or fancy quotation marks or mdash hyphens or similar, and this messes up the display of "git log" and other tools.

Add a check into commit-msg to reject commit messages that have non-ASCII characters. This does not apply to characters used in Signed-off-by: or similar fields that may contain people's names.
