/* General message writing routines.
** Each message is a single warning, error, etc.
**
** This routine will keep track of counts and,
** if the caller has set a filter, it will be
** called.  The new preferred way of handling
** Tidy diagnostics output is either a) define
** a new output sink or b) install a message
** filter routine.
**
** Keeps track of ShowWarnings, ShowErrors, etc.
