-o requires space for argument

[MithicSpirit]

curl -ofoo.html example.com correctly outputs to foo.html, but wcurl -ofoo.html example.com fails with Unknown option: '-ofoo.html'.. This seems to be because there is no handler for -o* (and -O*, though this behaves differently than from curl) in the argument parser. I suspect adding this (adapted from --output=) would work, and I can open a PR for it if desired.

        -o*|-O*)
            opt=$(printf "%s\n" "${1}" | sed 's/^-[oO]//')
            HAS_USER_SET_OUTPUT="true"
            OUTPUT_PATH="${opt}"
            ;;

Flagging this so I can discuss it with @sergiodj during FOSDEM this weekend.
