Leaving the edit summary on a new page blank gives it an automatic edit summary with much more detail. Something like "Created page with content: 'blah blah blah'" if I recall correctly.

...and yes, you can turn off the option to prompt for an edit summary in your preferences. If you are using the new visual editor, then there it no way around it. You hit publish and the edit summary dialog comes up no matter what your preferences are set to. …but you can just click publish without a summary and it publishes, so it doesn't feel like you have to do it twice 😆
