> Hello, I'm attaching a patch that enhances user experience when adding
> Gnus scores interactively based on date header. This patch does multiple
> things:
> 
> 1. `char-to-type' variable is renamed to `char-to-types' and we allow it
> to be mapped to multiple types. This is useful because date header
> supports all these types for scoring - '<, '>, 'r, 'after, 'before, 'at
> but only the last three were previously offered to the user when using
> interactive scoring.
> 
> 2. `gnus-summary-score-entry' now provides sensible defaults for each
> date scoring type - if we're scoring based on integer value ('<, '>) we
> offer number of days between now and entry at point (revised version of
> what was introduced in bug#61002) and if we're scoring based on string
> value ('after, 'before, 'at, 'r) we provide valid date string.
> 
> 3. If the user scores articles based on date strings ('before, 'after,
> 'at, 'r), `gnus-summary-score-entry' will no longer cast the type to the
> integer type.
> 
> 4. `gnus-score-date' catches 'r type as well.

> I'm also Cc'ing Alex who was the original author of '< '> date scoring
> types. Please let me know what you think.
