#2995: Mutt is folding subject line folds using a tab, which appears to be 
against
RFC 2822

 Mutt is folding long subject lines by using a CRLF and then a tab.

 For example, what was:[[BR]]

 Subject: A DSL modem belonging to username 'username' is constantly
 reconnecting (112 times)

 in the headers is now:[[BR]]

 Subject: A DSL modem belonging to username 'username' is constantly

 <Tab>reconnecting (112 times)

 That doesn't appear to be compliant with RFC 2822. According to
 section 2.2.3:

      Unfolding is accomplished by simply removing any CRLF
      that is immediately followed by WSP.

 Outlook does not remove the tab when unfolding, such that a huge gap in
 the subject line.  Now I know why some people's NANOG and other techie-
 type listservs are showing the occasional gap in the subject line -- they
 must be using mutt as their email client.

 This was not the behavior in 1.4.1i.

 I am sending messages from the command-line, if that makes a difference in
 the subject line processing.
