How many of the total number of ports have their distfiles served
by such servers? Would it be simpler to just not display a progress bar
in those cases, as opposed to introducing another keyword?
If the idea is to help display a progress bar (please make it in color),
why is it a 'checksum'? We already have much beter checksums.
curl it the one doing the download. If it can display a progress bar,
it will. If not, please leave it like that.
