 * $Log: remail.c,v $
 * Revision 5.10  1993/04/21  01:25:45  syd
 * I'm using Elm 2.4.21 under Linux.  Linux has no Bourne shell.  Each
 * user installs her favorite shell as /bin/sh.  I use Bash 1.12.
 *
 * Elm invokes the mail transport (MTA) like so:
 *
 *    ( ( MTA destination; rm -f tempfile ) & ) < tempfile &
 *
 * This form of command doesn't work with my Bash, in which any command
 * which is backgrounded ("&") gets its stdin attached to /dev/null.
 *
 * The below patch arranges for Elm to call the MTA thusly:
 *
 *    ( MTA destination <tempfile; rm -f tempfile ) &
 * From: decwrl!uunet.UU.NET!fin!chip (Chip Salzenberg)
 *
 * Revision 5.9  1993/04/12  02:34:36  syd
 * I have now added a parameter which controls whether want_to clears the
 * line and centers the question or behaves like it did before. I also
 * added a 0 at the end of the parameter list to all the other calls to
 * want_to where a centered question on a clean line is not desirable.
 * From: Jukka Ukkonen <[e-mail]>
 *
 * Revision 5.8  1993/01/20  03:37:16  syd
 * Nits and typos in the NLS messages and corresponding default messages.
 * From: [e-mail] (Dave Wolfe)
 *
 * Revision 5.7  1992/12/24  21:42:01  syd
 * Fix messages and nls messages to match.  Plus use want_to
 * where appropriate.
 * From: Syd, via prompting from Jan Djarv <[e-mail]>
 *
 * Revision 5.6  1992/11/26  01:46:26  syd
 * add Decode option to copy_message, convert copy_message to
 * use bit or for options.
 * From: Syd and [e-mail] (Bjoern Stabell)
 *
 * Revision 5.5  1992/11/26  00:49:04  syd
