+- Issue #11401: fix handling of headers with no value; this fixes a regression
+ relative to Python2 and the result is now the same as it was in Python2.
+
- Issue #9298: base64 bodies weren't being folded to line lengths less than 78,
which was a regression relative to Python2. Unlike Python2, the last line
of the folded body now ends with a carriage return.
