 Log Message:
 PR bin/51145 PR bin/48489
 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.
