- * Local helper routine to isolate a single token (option or argument)

- *
- * This routine accepts a pointer to a character pointer. The first
- * token (as defined by MSDN command-line argument syntax) is isolated
- * from that string.
- *
- * Upon return, the input character pointer pointed to by the parameter s
- * is updated to point to the remainding, unscanned, portion of the string,
- * or to a null character if the entire string has been consummed.
- *
- * This function returns a pointer to a null-terminated string which

- *
- * Note the side effect of modifying the input string s by the insertion
- * of a null character, making it two strings.
- *
- * See "Parsing C Command-Line Arguments" in the MSDN Library for the
- * parsing rule details. The rule summary from that specification is:
- *
- * * Arguments are delimited by white space, which is either a space or a tab.
- *
- * * A string surrounded by double quotation marks is interpreted as a single
- * argument, regardless of white space contained within. A quoted string can
- * be embedded in an argument. Note that the caret (^) is not recognized as
- * an escape character or delimiter.
- *
- * * A double quotation mark preceded by a backslash, \", is interpreted as a
- * literal double quotation mark (").
- *
- * * Backslashes are interpreted literally, unless they immediately precede a
- * double quotation mark.
- *
- * * If an even number of backslashes is followed by a double quotation mark,
- * then one backslash (\) is placed in the argv array for every pair of
- * backslashes (\\), and the double quotation mark (") is interpreted as a
- * string delimiter.
- *
- * * If an odd number of backslashes is followed by a double quotation mark,
- * then one backslash (\) is placed in the argv array for every pair of
- * backslashes (\\) and the double quotation mark is interpreted as an
- * escape sequence by the remaining backslash, causing a literal double
