# done with a client that does or does not respect the Content-disposition
# HTTP header. Browsers usually do, wget doesn't, unless it's instructed
# to (via command line option or wgetrc). handle both filenames here.
# for github, there's a "magic" URL that gives us the same filename
# either way, but this isn't a github project.
