scriv collect always creates changelog entry even if nothing has changed

[sysid]

@nedbat, thanks for contributing this tool.

I observed a surprising behavior when running scriv collectseveral times in a row: Every run of scriv collectcreates a new entry in changelog.md even without a new fragment or changed version number. This results in empty and redundant entries in changelog.md.

Without a new fragment I would not expect to get a new entry in changelog.md. Maybe I am missing something. Regards, sysid
