Use the user's current locale to format dates (e.g.: based on LC_ALL or
LC_TIME). Given that dates have variable lengths, move them onto their
own separate line.

Hi,

Thanks for your patch.

However, I'd like to have dates kept very short (5 charts only), and to 
avoid putting dates on their own lines.

Typically on low-traffic channels you can sometimes have 1 date per message.

Just adding the year of dates would not be worth halving the density of 
messages.
