I wrote an &ngmatch function in perl that handles this "correctly". It uses the best match, where "best" is defined as the one with the least number of pieces matching "all". The other thing B news matches that C news doesn't is patterns like "comp.all.binaries". (My perl function doesn't handle this yet.) -- Felix Lee flee@shire.cs.psu.edu *!psuvax1!flee
