Yet another issue where the conversion of the application delimiter to comma caused an issue.

Application arguments within the feature map could possibly contain a comma,
which conflicts with the syntax of the features.conf configuration file.  This
patch allows the argument to be wrapped in parentheses or quoted, to allow the
application arguments to be interpreted as a single configuration parameter.
