Euphoria Ticket #728: invalid parameters is caught in the backend rather than the front end.

random parameters without an extra causes an error that doesn't get caught until it reaches the backend. This after the fixes for ticket 725 were successful.


$ echo > t_null.e 
Shawn@Joy-PC /cygdrive/c/Users/Shawn/Docu 
$ eui -foo t_null.e 
Fatal run-time error: 
slice length is less than 0 (-2)

It's a problem in the way we slice up the command line argument sequence. It is actually in the front end where the problem occurs.

$ ../4.0/eui ../source/int.ex -foo t_switch.e 
source/cominit.e:423 in function expand_config_options()  
slice length is less than 0 (-2)
