Andrew,
I cannot reproduce your result unless I do this:
% x="-l -d"
% ls "$x"
ls: invalid option --
Try `ls --help' for more information.
I tried using hard (single) quotes for the variable setting command, but
the result is the same. Likewise for $'-l -d'.
I also tried using /bin/sh (ash, I believe), but again I cannot reproduce
your erroneous result.
I tempted to chalk this up to some kind of operator error...
