#3385: First letter of header fields with no space after colon gets suppressed
--------------------+-------------------------------------------------------
 Reporter:  bisson  |       Owner:  mutt-dev
     Type:  defect  |      Status:  new     
 Priority:  major   |   Milestone:          
Component:  mutt    |     Version:  1.5.20  
 Keywords:          |  
--------------------+-------------------------------------------------------
 Header fields such as "Subject:Message for you" (i.e. no space after
 colon) do not seem to violate RFC822; however, Mutt displays them as
 "Subject: essage for you" (replacing the first letter by a space).

 Tested with mutt-1.5.20 (i686) over a maildir containing the file
 attached.
