+Subject: [PATCH] option: add option to disable Want-Digest header
+
+Sending this HTTP header should be optional.
+Should close https://github.com/myfreeer/aria2-build-msys2/issues/10
+
+ --http-want-digest[=true|false] Send Want-Digest HTTP requser header
+                              with only limited hash algorithms:
+                              SHA-512, SHA-256, and SHA-1.
+                              The Want-Digest HTTP header is primarily used
+                              in a HTTP request, to ask the responder to
+                              provide a digest of the requested resource
+                              using the Digest response header
+
+                              Possible Values: true, false
+                              Default: true
