We solved this on IRC. Turns out "-interface" was truly used exactly like that
and not with the proper two dashes: --interface.

By an interesting coincidence, "-interface" is a series of single-letter
options that work fine to put next to each other like that without any error.
It then makes the following "192.71.23.48" to be treated as a URL and curl can
proceed.

I'm considering if it would make sense to add a warning output to the option
parser in case -[string] happens to exacly match a --[string] option, since it
is then often this mistake being done.
