More fixes to the shell parser to prevent empty simple commands (where
empty means no significant text at all) - as discussed on tech-userlevel
this still allows { } (which can be useful in function definitions, not
really anywhere else though) except in posix mode.  ( ) now generates
a syntax error, as should any other place where commands are required but
nothing is present.  (nb, redirections, var assignments, even var expansions
that expand to nothing, are all OK, and avoid the error - just comments, or
whits space, are not.)    This is (aside from allowing { } at all) all in
accordance with the posix spec.
