Re: GraphicsMagick file globbing fixes

I notice that there are existing memory leaks related to the argument
vectors which are now more obvious due to ExpandFilenames always
returning a new argument vector allocation (it used to be conditional
based on whether tilde expansion or globbing had been performed).  I
will attend to these today.
