Ok.  The LogReader command has a mechanism to filter which tablet is
displayed.  If the walog has  alot of data in it, may need to use
this.

Also, be aware that only 5 mutations are shown for a "many mutations"
objects in the walog.   The -m options changes this.  May want to see
more when deciding if the info in the log is important.
