I didn't mean to, though I don't promise I didn't send something buggy.
It looks right to me, though:
if (opts.show_progress < 0) { /* if the user didn't say... */
if (opts.quiet)
opts.show_progress = 0; /* quiet means "no progress" */
else
opts.show_progress = isatty(2); /* returns 0/1 bool */
}

That's standard. And "1" is "--progress".

The difference between mine and yours is that in mine, "--progress"
trumps "--quiet", whereas it is the other way around in yours. I don't
know if it is a huge deal, but mine makes more sense to me (because
"--progress" is more specific than "--quiet", which might silence other
messages, too).
