Added a few lines to the setup file parser so that if there is a

missing brace in the file (a common error), then the fact that
there is an unevaluated command when the file has finished being
read will trigger an evaluation of the unfinished code and emit
an error.  Previously, the command and anything after the
unterminated brace would just silently get ignored, which was not
helpful for debugging setup syntax errors.
