No reason.  I was just trying to be careful, not leaving data in the
upper bits of those registers going uninitialized.  If we know they're
not being used ever, then it's not a problem.  But I don't think
that's the source of the command line size concern, is it?


Since the cmd_line_ptr is 32bit, we can load the lower 16bits into si,
ignoring the upper 16bits, or we can use esi for all references.
I think using esi for all references is cleaner...
