   Like some others, when I see such stuff getting out of hand, I go in
   manually and change 1-5, 7, 9-11, 13 to 1-13 (for example). It would be
   good if there were a tool to do that automatically--take the first and last
   number in a newsgroups's .newsrc entry, and replace the stuff in between with
   a dash.

sed 's/\([:'\!']\) *\([0-9]*\).*[,-]\([0-9]*\)$/\1 \2-\3/' \
	< .newsrc > .newsrc.new

You can reduce the size of your .newsrc even more by eliminating *all*
numbers on newsgroups to which you do not subscribe:

sed -e 's/\([:'\!']\) *\([0-9]*\).*[,-]\([0-9]*\)$/\1 \2-\3/' \
	-e 's/'\!'.*/'\!' /' \
	< .newsrc > .newsrc.new
