Tokenize the arguments for rewrite programs during config parsing, and

just use that information later.  I was having a problem with prg
directives with arguments failing the configuration.  The problem was
a call to stat, which was being passed the program name and the arguments.
Obviously, the arguments were messing up the call to stat.  This gets the
test suite working for me again.
