Inconsistency between git-log documentation and behavior regarding default date format.

The Git documentation <https://www.git-scm.com/docs/git-log#Documentation/git-log.txt---dateltformatgt> states that if no date format is given (or --date=default is given), the date format is similar to rfc2822 except of a few exceptions, of which those listed are:

   * There is no comma after the day-of-week
   * The time zone is omitted when the local time zone is used

However, if we were to compare the two date formats, you can see another difference:

git log --default  ->  Tue Jan 24 11:03:47 2023 +0100 git log --rfc          ->  Tue, 24 Jan 2023 11:03:47 +0100

With the default, the month and day-of-month are switched around. From my own quick investigation, this behavior occurs because of the statement found at date.c#L266 <https://github.com/git/git/blob/56c8fb1e95377900ec9d53c07886022af0a5d3c2/date.c#L266> wherein the month is inserted before the day-of-month. I am unsure which behavior is exactly intended and whether this discrepancy was known, but it would probably be a good idea to have a note of it in the documentation.
