Blog post date-only format

[alexvoss]

Context

Use of the blog plugin without further settings.

Bug description

As discussed in #6998 (reply in thread), the post date by default contains a time was well, which is set to 12:00AM. It should display only a date, regardless of whether the page header contains only a date or a date and time. This has also been observed in #6996.

While is is possible to fix this through customization, the default should be only the date.

Note that the default was date only as late as 9.5.13+insiders.4.53.1.

Thanks for reporting. This is a regression of accepting and merging #6981, which switched to format_datetime instead of format_date. The predefined format long will now refer to a format string that includes the time. Rendering the blog post without time should be the default, as our current assumption is that that's what most users would expect.

1041766 adds a condition that checks if the author uses one of the predefined time formats, the blog plugin should use format_date. However, if a custom string is given, the plugin will make use of format_datetime, so we allow explicitly opting into using format strings including time. This still fixes #6981 but allows us to keep sensible defaults.
