+Subject: [PATCH] http2: fix EOF handling on uploads with auth negotiation
+
+- doing a POST with `--digest` does an override on the initial request
+  with `Content-Length: 0`, but the http2 filter was unaware of that
+  and expected the originally request body. It did therefore not
+  send a final DATA frame with EOF flag to the server.
+- The fix overrides any initial notion of post size when the `done_send`
+  event is triggered by the transfer loop, leading to the EOF that
+  is necessary.
+- refs #11194. The fault did not happen in testing, as Apache httpd
+  never tries to read the request body of the initial request,
+  sends the 401 reply and closes the stream. The server used in the
+  reported issue however tried to read the EOF and timed out on the
+  request.
