commit 76e7b503d2dde98f3d9d3a580108f23e68aa8082

    Work around libfetch bug in FreeBSD 12.
    
    When an HTTP URL returns a redirect to an HTTPS URL and the HTTPS URL
    is accessed through a proxy, the proxy syntax (GET https://...) is used
    in the request to the origin server. Some servers cannot deal with this.
    
    This bug was fixed in -CURRENT in 2018 (git commit a768df3e91) but is
    still present in 12-STABLE and all 12 releases.
