Force-pushes above were for fixing minor issues I have overlooked, such as extra semicolon, etc.

Hi, thanks for the PR!

Why do you think this is useful?

Hi, two reasons occur to me:

1. Let's say all my log messages start with a capital letter — the default message doesn't. I know this is more of a stylistic concern than a functional one.
2. Language localization — perhaps I have a server that logs messages in a language other than English. This change would help keep the logging consistent.

I'm not really convinved this is worth adding, you can easily wrap this module in another and add whatever option validation you need.

Without a real use case I think we have to reject your proposal.
