-Subject: [PATCH 4/8] Error when receiving back Chunk Extension
-
-Waitress discards chunked extensions and does no further processing on
-them, however it failed to validate that the chunked encoding extension
-did not contain invalid data.
-
-We now validate that if there are any chunked extensions that they are
-well-formed, if they are not and contain invalid characters, then
-Waitress will now correctly return a Bad Request and stop any further
-processing of the request.
-

+Subject: [PATCH] Error when receiving back Chunk Extension
+
+Waitress discards chunked extensions and does no further processing on
+them, however it failed to validate that the chunked encoding extension
+did not contain invalid data.
+
+We now validate that if there are any chunked extensions that they are
+well-formed, if they are not and contain invalid characters, then
+Waitress will now correctly return a Bad Request and stop any further
+processing of the request
