Nice.  Thanks for working on this.

The string() command implementation can be refactored out into
an internal helper as you propose.  That internal helper will
need to define an abstraction for the error cases so that the
cmGraphVizWriter can capture the errors too.  Then the string()
implementation can capture them and transform them back into
the original error messages.
