"" is used to seperate arguments, not to prevent them from being
interpreted.  Applications get given a list of arguments eg:

./foo bar baz narf
gets given ["./foo","bar","baz","narf"]

./foo "bar baz" narf
gets given ["./foo","bar baz","narf"]

./foo "/et*" foo bar
gets given ["./foo","et*","foo","bar"]

./foo /et* foo bar
gets given ["./foo","/etc","foo","bar"]
