The problem I think you're running into is the 256-char limit on the
command line constructed in checkgroups and handed to egrep.
Hello?  Do I hear GNU calling?  (Don't ask me.)
The workaround I used was to chop up the input to checkgroups
into tiny little bits (like, about 20) and feed those little bits
into checkgroups.  I would separate all rec.* into one file, for example,
all talk.* into another, etc.  The script still did bad things with
comp.*, however.  It produced a script to delete a whole lot of the
*.sources and *.binaries groups, even though they existed in the
new newsgroups file I had brought in.  Some hand-editing before
running the script cleared that up.

So....
A new egrep for checkgroups?
