Small addition to dia-list subject line

[Jacek Pliszka <pliszka phyun0 ucr edu>]

Hi!

What do you folks think about adding to e-mails distributed through 
dia-list a [dia-list] in the subject ?

So the title of this e-mail would be:

[dia-list] Small addition to dia-list subject line

What do you think about adding it to the list config so it
is done automatically by mailman ?

BR,

Jacek
