zero ("'0'") character enables sign-aware zero-padding for numeric

presentation types.

-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.
