Shawn Rutledge b922c97c9c TextEdit example: add indent/unindent feature
It was not possible to interactively create the example text without
this feature; and in general it's necessary to work with nested lists.
But currently it does not deal with all possible changes of list nesting,
because the API seems incomplete for that purpose.
