quick fix for this bug

When you write a variable that is not previously defined (or is empty) in the command line hush crashes.

For example:
/home/user $ $notdefined

crashes hush

I've attached a patch that prevents this from happening, not sure if it should be the final solution though.

Thanks,

Mikel

Can't reproduce:

# ./busybox hush
/usr/srcdevel/bbox/fix/busybox.t5 # /home/user $ $notdefined
hush: can't execute '/home/user': No such file or directory
/usr/srcdevel/bbox/fix/busybox.t5 #

Hi, 

sorry for the misunderstanding, the "/home/user$ " suppose to be the prompt. The actual command should be:

$whatevernotdefinedvariable

thanks for the quick response,

Mikel
