Yeah, there is no foolproof way to do this short of implementing a parser
that acts exactly as the shell itself would when parsing the command line.

The more I think about this, the more I think I am just going to look for the
string 'sudo' anywhere in the argument.  This merely will force the user to
enter their sudo password if detected.  If it turns out to be a false positive,
no harm will be done and the password will just go unused.


Thanks for the feedback.
