- gh-135661: Fix parsing start and end tags in
html.parser.HTMLParser according to the HTML5 standard.
* Whitespaces no longer accepted between </ and the tag name. E.g.
</ script> does not end the script section.
* Vertical tabulation (\v) and non-ASCII whitespaces no longer
recognized as whitespaces. The only whitespaces are \t\n\r\f and
space.
* Null character (U+0000) no longer ends the tag name.
* Attributes and slashes after the tag name in end tags are now
ignored, instead of terminating after the first > in quoted
attribute value. E.g. </script/foo=">"/>.
* Multiple slashes and whitespaces between the last attribute and
closing > are now ignored in both start and end tags. E.g. <a
foo=bar/ //>.
* Multiple = between attribute name and value are no longer
collapsed. E.g. <a foo==bar> produces attribute “foo” with value
“=bar”.

- gh-121284: Fix bug in the folding of rfc2047 encoded-words
when flattening an email message using a modern email
policy. Previously when an encoded-word was too long for
a line, it would be decoded, split across lines, and
re-encoded. But commas and other special characters in the
original text could be left unencoded and unquoted. This
could theoretically be used to spoof header lines using a
carefully constructed encoded-word if the resulting rendered
email was transmitted or re-parsed.
- gh-80222: Fix bug in the folding of quoted strings
when flattening an email message using a modern email

it spanned more than one line, the surrounding quotes and

be used to spoof header lines using a carefully constructed
quoted string if the resulting rendered email was transmitted
or re-parsed.
