bug#61002: 28.2; Gnus - "Date" scoring scores all articles.

["Jakub Ječmínek" <jecminek.k@gmail.com>]

I've made huge mistake in my previous patch (now everyone will know
that I'm terrible programmer).

Here's working solution of what I'm proposing:

Subject: [PATCH] Provide valid match element for date key during interactive
 gnus-summary-increase-score

* lisp/gnus/gnus-score.el (gnus-summary-score-entry): The user is given invalid
default match element value during interactive use of gnus-summary-increase-score
and gnus-summary-lower-score (date key). We fix that by providing more meaningful
default value - number of days between today and entry at point.
