	If you want all of the numbers back to 1, you can go into the
group with `C-u SPC', turn off threading with `T T', sort the articles
in a reasonable order `C-c C-s C-n' then using `C-u ### B m' refile
everything into a _new_ group (where ### is large enough to cover all of
the articles).  Then you can go and rename & remove the original group,
and then rename the new group to the old name.

	If you just want the group compacted, but not starting at
article number 1, you can just refile into the same group rather than
a new one.


	Oh, and if you use the cache, be careful that everything works
right.  I think I've noticed that renaming a group doesn't always rename
the cache.


Anyone have better thoughts on this?  Considering how slow total-expire
currently gets with groups with lots of holes, maybe a safe compaction
routine should be added to Gnus itself.
