/* ### Modified by P.Saratxaga on 7 Aug 1995 ###
* - Newsgroups: line is now gated if there is more than one newsgroup
* - Added support for X-FTN-To and X-FTN-From generated by other gates
* - modified removemime to kludgerise lines if charset != us-ascii
* - creation of ^aACUPDATE kludges from Supersedes: and cancel's
* - added charset support (see Changelog for details)
* - added recognition of X-Fsc-
* - added support to dequote MIME quoted printable messages. Code by T.Tanaka
* - added removemsgid and removeinreply
