No, pathprune would not strip this out.  It will only strip out machines
if their domain gateway has the same leading path.  If you are interested,
I'll send you a shar of the whole thing, or you can pick it up from
your nearest net.sources archive.

Here is an excerpt from the man page:
...
          This can more easily explained by example.  Assume the input
          of:
               .com           ncr-sd!scubed!seismo!%s
               .ncr.com       ncr-sd!%s
               .sandiego.ncr.com   ncr-sd!%s
               .other              ncr-sd!%s
               .uucp               ncr-sd!%s
               falstaf.sandiego.ncr.com ncr-sd!falstaf!%s
               ncr-sd.sandiego.ncr.com  ncr-sd!%s
               se-sd.sandiego.ncr.com   %s
               tower5.sandiego.ncr.com  tower5!%s
          After processing, the output will be:
               .com           ncr-sd!scubed!seismo!%s
               .ncr.com       ncr-sd!%s
               .other              ncr-sd!%s
               .uucp               ncr-sd!%s
               se-sd.sandiego.ncr.com   %s
               tower5.sandiego.ncr.com  tower5!%s
          The domain gateway  .sandiego.ncr.com  was  removed  because
          .ncr.com  will  get  us to the same place.  If the -t option
          had been specified the .com and .ncr.com gateways would also
          have  been  removed.  All hosts that lie beyond the .ncr.com
          (or .other for  -t)  gateway  were  also  removed  as  being
          unnecessary.
