Subject: [PATCH] Use GET rather than HEAD when checking for range support in
 curl_download.    * Some HTTP servers apparently support ranges but don't
 support HEAD.    * This is a more realistic check anyway since the actual
 download request      will use GET (not HEAD).    * This fixes
 Homebrew/brew#5420.
