Well it's actually a little more complicated than this, anyway the
point was to avoid the need to create a script for something which can
be done by adding an option, also I'm quite sure there are other
shells out there which suffer the same limitation (command.com just to
say one... and no not having this feature is not a reason for changing
a shell).
