+Subject: [PATCH] http: with chunked POST forced, disable length check on read
+ callback
+
+- when an application forces HTTP/1.1 chunked transfer encoding
+  by setting the corresponding header and instructs curl to use
+  the CURLOPT_READFUNCTION, disregard any POST length information.
+- this establishes backward compatibility with previous curl versions
+
+Applications are encouraged to not force "chunked", but rather
+set length information for a POST. By setting -1, curl will
+auto-select chunked on HTTP/1.1 and work properly on other HTTP
+versions.
+
+Reported-by: Jeff King
+Fixes #13229
+Closes #13257
+Upstream-Status: Backport
