 curl versions from 7.37.0 (2014) up to but not including 7.82.0 (2022)
 fail to handle the situation where a web site's canonical hostname ends
 with a period. See https://github.com/curl/curl/issues/8290. Here is an
 example of the problem:
 {{{
 % /usr/bin/curl --version
 curl 7.79.1 (x86_64-apple-darwin21.0) libcurl/7.79.1 (SecureTransport)
 LibreSSL/3.3.5 zlib/1.2.11 nghttp2/1.45.1
 Release-Date: 2021-09-22
 Protocols: dict file ftp ftps gopher gophers http https imap imaps ldap
 ldaps mqtt pop3 pop3s rtsp smb smbs smtp smtps telnet tftp
 Features: alt-svc AsynchDNS GSS-API HSTS HTTP2 HTTPS-proxy IPv6 Kerberos
 Largefile libz MultiSSL NTLM NTLM_WB SPNEGO SSL UnixSockets
 }}}
 {{{
 % /usr/bin/curl -I https://pyropus.ca./
 HTTP/1.1 301 Moved Permanently
 Date: Mon, 03 Apr 2023 01:17:16 GMT
 Server: Apache/2.4.56 (Debian)
 Location: https://pyropus.ca./
 Content-Type: text/html; charset=iso-8859-1
 }}}

 The memtester port is an example that fails to fetch distfiles because of
 this (if the `master_sites` override is removed from the Portfile). It
 also fails livecheck.

 It was pointed out to me by the author of memtester that affect curl
 versions can be made to work by setting the `Host` header properly, as in:

 {{{
 % /usr/bin/curl -H 'Host: pyropus.ca.' -I https://pyropus.ca./
 HTTP/1.1 200 OK
 Date: Mon, 03 Apr 2023 01:18:35 GMT
 Server: Apache/2.4.56 (Debian)
 Accept-Ranges: bytes
 Vary: Accept-Encoding
 X-Frame-Options: sameorigin
 Content-Type: text/html
 }}}

 MacPorts should use a regexp to extract the host out of the URL and set
 the Host header every time it invokes curl for any purpose to work around
 buggy curl versions.
