+       * monitor.c (monitor_debug): Take prefix, and suffix arguments.
+       Print trailing newline after the suffix.
+       (monitor_printf{,_noecho}): Change monitor_debug calls.
+       (monitor_printf): Call monitor_expect instead of trying to do the
+       expect processing locally so that if there is extra junk, it
+       doesn't hang things up.
+       (readchar): If MO_HANDLE_NL is set, handle \r\n pairs and convert
+       them to a single \r.  Use monitor_debug to print out byte read.
+
+       * monitor.h (MO_HANDLE_NL): Add new flag.
+
+       * ppcbug-rom.c (ppcbug_ops{1,2}): Split into two ops, one that
+       uses lo 0 to load, and the other that uses lo 1.  Set flag
+       MO_HANDLE_NL.
+       (ppcbug_open{0,1}): Clone and split to handle ppcbug_ops{1,2}.
+       (_initialize_ppcbug_rom): Set up both ppcbug_open{0,1}.

        * defs.h: Delete extraneous whitespace at end of file.
