//////////////////////////////////////////////////////////////////////////////
//
// FormatMbox class returns consecutive lines from the current message,
// formatted for delivery into a mailbox. That means the lines are
// terminate with either <LF> or <CRLF> (defined at compilation time).
// Furthermore, the message can be optionally preceded by the From line.
//
// Mandatory calling sequence:
//
// int HasMsg() - return 0 if there's a message to deliver, or -1 if
// the message is empty (none).
// void Init(flag) - initialize. Flag is non-zero if the message is to
// have a From line (and embedded From lines to be
// escaped). Flag is zero if the message should not
// be molested by From lines (when writing to a pipe).
// Buffer NextLine() - return consecutive lines, until a NULL pointer is
// returned.
//
// When NULL pointer is returned, the hdrfrom, hdrsubject, and msgsize will
// contain message information (suitable for logging).
