+Subject: [PATCH] Upon HTTP_1_1_REQUIRED, retry the request with HTTP/1.1
+
+This is a companion patch to cbea2fd2c (NTLM: force the connection to
+HTTP/1.1, 2018-12-06): with NTLM, we can switch to HTTP/1.1
+preemptively. However, with other (Negotiate) authentication it is not
+clear to this developer whether there is a way to make it work with
+HTTP/2, so let's try HTTP/2 first and fall back in case we encounter the
+error HTTP_1_1_REQUIRED.
+
+Note: we will still keep the NTLM workaround, as it avoids an extra
+round trip.
+
+Daniel Stenberg helped a lot with this patch, in particular by
+suggesting to introduce the Curl_h2_http_1_1_error() function.
+
+Closes #3349
