Yay for consistency. $Subject says 'Add option to force wait'. Changelog
says 'Add option to skip ... check'. Can you make your mind up?

Also the change at hand is not adding an option. It's adding a function
argument. You surely can spot the difference between option and function
argument, right?

Changelogs are meant to be readable by mere mortals.

Thanks,
