Comment (by awbauer):

 Actually, just discovered that tapping into the `http_api_curl` action
 provides a functioning workaround.

 {{{#!php
 <?php
 function bu_http_api_curl( $handle, $r, $url ) {
         if ( ! empty( $r['body'] ) || 'POST' == $r['method'] || 'PUT' ==
 $r['method'] ) {
                 unset($r['headers']['Content-Length']);
                 curl_setopt( $handle, CURLOPT_HTTPHEADER, $r['headers'] );
         }
 }
 add_action( 'http_api_curl', 'bu_http_api_curl', 10, 3 );
 }}}
