   I'm usinge the nnml backend to read my mail. To get rid of read mail,
   I either expire the article or use B DEL. When I have received more
   than 200 articles in a nnml group, I get prompted for how many
   articles to show when entering it. The problem is that there are only
   about 20 articles present in the group and it's quite annoying to get
   prompted for this every time. Is there a way to fix this without
   setting gnus-large-group to something very high? Can you somehow
   renumber the articles in a group? I'm using Gnus 5.2.1.

   Enter the group, mark all articles, and then move them all to the
   current group. If they were spread out between 1 and 200, they will
   now all be numbered consecutively starting at 201.
   
   In response to the further question: Can this be done without breaking
   the xref info?

   Well -- if these are Xreffed from a different group, this'll break the
   Xref info in the other groups. That is, if you (after renumbering the
   articles) read the articles in a different group, they won't be marked
   as read in the renumbered group.
