+ * Format a module id for printing.
+ *
+ * There are three possible formats:
+ *
+ *   MODULE_FORMAT_BRIEF       is the brief 6-character format, including
+ *                             the actual brick-type as recorded in the 
+ *                             moduleid_t, eg. 002c15 for a C-brick, or
+ *                             101#17 for a PX-brick.
+ *
+ *   MODULE_FORMAT_LONG                is the hwgraph format, eg. rack/002/bay/15
+ *                             of rack/101/bay/17 (note that the brick
+ *                             type does not appear in this format).
+ *
+ *   MODULE_FORMAT_LCD         is like MODULE_FORMAT_BRIEF, except that it
+ *                             ensures that the module id provided appears
+ *                             exactly as it would on the LCD display of
+ *                             the corresponding brick, eg. still 002c15
+ *                             for a C-brick, but 101p17 for a PX-brick.
+ *
+ * maule (9/13/04):  Removed top-level check for (fmt == MODULE_FORMAT_LCD)
+ * making MODULE_FORMAT_LCD equivalent to MODULE_FORMAT_BRIEF.  It was
+ * decided that all callers should assume the returned string should be what
+ * is displayed on the brick L1 LCD.
