The technical term to refer to these From/Subject/Date override is
"in-body header", and using it would make it easier to tell what the
commit is about when this appears in "git shortlog" output.  Perhaps

	am: document that Date: can appear as an in-body header

When the general public sees the patch for the first time is when
the patch is authored as far as the participants of this list are
concerned.

Please don't lie about the author date on this list.

Correct.  It would be a good idea to fix "will be preferred" in the
proposed log message to match this by reusing the verb "override".
Perhaps like

	Similar to "From:" and "Subject:" already mentioned in the
	documentation, "Date:" can also appear as an in-body header
	to override the value in the e-mail headers.  Document it.
