Hi,

    A day ago I subscribed to handfull of new mailing lists and when I
    was away last night my procmail recipes sorted them to wrong folders.
    so I had to move lot of mail from group to another.

    The first command that come into my mind was 

	gnus-uu-mark-by-regexp

    But it only matched subjects. I assumed it would match the 
    visible Summary line, but it didn't :-). There was nothing in common
    in the subject lines that come from eg liserv XXX. However If I
    matched against From field, then I could tag all the messages
    coming from particular list and move then all to right group.

    Here is the new functions that do that: They un/mark articles
    that match From field. The patch is against 5.6.38. Feel free
    to move the new keybinds to somewhere more appropriate.
