Note 21Sep2007 by Dominik Reichl, edited by Bill Rubin:

The isSpace() function fixes a recently-discovered subtle bug caused by
failure to properly convert characters to int before passing to std::isspace.
Microsoft's CRT 2005 implementation of isspace asserts that the incoming
character (of type int) is nonnegative.  When the application is compiled 
in ANSI mode, passing high ( > 127) ANSI codepage-dependent characters 
(like '�') directly to isspace, a negative value is passed as function parameter 
(automatic conversion from char to int), thus causing the assertion to fail. 
This can be avoided using the to_int_type function,
which correctly converts the char into an int in range 0 to 255.
*/

    /*
    As long as operator>>() returns with valid istream,
    it will be called again.  Once it has caused istream to
    become invalid, it will not be called again.
    After returning with invalid stream,
    stream iterator compares equal to default stream iterator,
    thus preventing copying of last token to token container.

    Parts of this function were modelled loosely after code in 
    Stroustrup's "C++ Programming Language" (Special Edition), 
    Sect. 6.1.3, p. 115.

    The constructor gets the command line, converts it to an istringstream,

    which interprets everything as a Token.  The iteration occurs while
    the copy algorithm copies the stream to the token-container.

    The SENTINEL value assures that last streamed character is blank.
    If the original command line has no unmatched quote, the blank 
    terminates the last token.  If the original command line has 
    an unmatched quote, the blank does not terminate the last token,
