Thanks, all good suggestions. For --dired vs --zero I thought it better 
simply to prohibit the combination since neither should be in 'ls' shell 
aliases, and prohibiting means we can add it later if we like. I 
installed the attached patches to do this (plus the other stuff I 
mentioned in my reply to Berny).

The first patch is a cleanup because I had a bit of trouble following 
the forest of 'if's inside of ls.c's decode_switches function and I 
thought it better to avoid unnecessary syscalls while I was at it.

The second patch does the real work.
