Summary: FeedParser does not comply with RFC2822

Initial Comment:
FeedParser (from Lib/email/FeedParser.py) uses  
the regular expression: 
 
^(From |[\041-\071\073-\176]{2,}:|[\t ])   
 
to recognise Mail headers.  However RFC2822   
says:   
 
field-name := 1*ftext   
 
which would give the regular expression:   
 
^(From |[\041-\071\073-\176]{1,}:|[\t ]) 
 
This causes mails that use single character 
header field names to be parsed incorrectly.
