If people think this is a good idea (and I am not one of those people),
then this wording is much too vague.  At least one shell implements '-a'
and '-o' as unary primaries, whereas what you mean by this patch is
almost certainly to mandate support of '-a' and '-o' as binary logical

Again, the list operators "&&" and "||" can handle any legitimate need
addressed by the -a/-o binaries.
