Granted there are problems, but similarly argv is subject to so much

Use argv.

Maybe it would notice that argv[0] didn't match the first token of the
variable.  But more likely, it would probably do something horrible.  :-)

Anyway, as I said, I'm not really lobbying for this, but just tossing
out ideas to kick around.
