Fixed issue #4 with tangler.

The tangler was getting lost if the character
after the word was ANSI.  (index -1).

render had some missing - values for MYSTIC[].
(Code is unused, but still needed to be fixed!)

Update CMakelists so changing a comment moves
the debug buffers off and on.

CharMan::~CharMan diagnostics() for the win!
