attr_repair.c has many printf-tracepoints under
#ifdef XR_DIR_TRACE, but the similar code in dir2.c does not.
Add these same tracepoints to remove more differences between
these two pieces of code.
Not all messages are quite correct; those will be fixed up last.
For now we just make the code more obviously similar.
