This makes me wonder if option_progress and o->quiet change once
parse_options() finished doing its job. If we know that these two
will never change once parse_options() is done, then we can
introduce a variable "show_progress", assign the value of that
variable to opts.verbose_update in these places and then arrange
that variable is set to the combination of quiet, option_progress
and isatty(2) just once after parse_options().
That is, something like this on top of Edmundo's patch.
