   There are two different use cases for this file:
   * Flags are permanently set by calling Set().
   * Flags can be temporarily set for a particular set of unit tests.  These
     tests should call Restore() to revert the flags to their original state
     once the tests have completed.

     Follows similar logic to CommandLine.java::tokenizeQuotedArguments:
     * Flags are split using whitespace, unless the whitespace is within a
       pair of quotation marks.
     * Unlike the Java version, we keep the quotation marks around switch
       values since we need them to re-create the file when new flags are
       appended.
