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...
