That won't work if you build any command other than this one. The union  
is defined in the headers of every command's c file, so the type has to  
be in lib.h for you to use it in GLOBALS. And I'd rather not pollute  
lib.h with a lot of command-local types...

Easy fix is just use a void * in GLOBALS and cast it to a local you  
actually use. (I've considered adding a generic list type that's a  
struct with just a next *, but you'd still have to typecast to use it,  
so it wouldn't help much.)

(P.S: I've got your pass 3 patch saved but I'm moving laptops and  
everything's in a halfway state that makes pushing changes to the  
website a bit funky just now. Hope to have that cleared up by monday.)
