At work, we have a machine that runs linux (I forgot which flavour). I had to do some stuff recently and I noticed by accident that VI that is installed there supports automagic gz file edition. By that I mean that when the file contains text, and it is gzipped, and I open it with VI, it displayes the uncompressed text data. This is quite handy. Do you know how one can confgure / tweak his VI to do sth like that?
