Shell - argv parameter with SPACE

[Richard Gaskin]

JB, a few of these snippets have been posted to the list, but with no 
explanatory text.  Were these intended for someone else?

If you meant to send them here, for the benefit of those of us who may 
not have ready access to an Objective-C compiler, would you mind 
offering some description of what we should be learning from these?
