- * Common function used to parse constructor arguments for VError, WError, and

- *
- *     strict		force strict interpretation of sprintf arguments, even
- *     			if the options in "argv" don't say so
- *
- *     argv		error's constructor arguments, which are to be
- *     			interpreted as described in README.md.  For quick
- *     			reference, "argv" has one of the following forms:
- *
- *          [ sprintf_args... ]           (argv[0] is a string)
- *          [ cause, sprintf_args... ]    (argv[0] is an Error)
- *          [ options, sprintf_args... ]  (argv[0] is an object)
- *
- * This function normalizes these forms, producing an object with the following
- * properties:
- *
- *    options           equivalent to "options" in third form.  This will never
- *    			be a direct reference to what the caller passed in
- *    			(i.e., it may be a shallow copy), so it can be freely
- *    			modified.
- *
- *    shortmessage      result of sprintf(sprintf_args), taking options.strict
- *    			into account as described in README.md.

-	 *
-	 * extsprintf (which we invoke here with our caller's arguments in order
-	 * to construct this Error's message) is strict in its interpretation of
-	 * values to be processed by the "%s" specifier.  The value passed to
-	 * extsprintf must actually be a string or something convertible to a
-	 * String using .toString().  Passing other values (notably "null" and
-	 * "undefined") is considered a programmer error.  The assumption is
-	 * that if you actually want to print the string "null" or "undefined",
-	 * then that's easy to do that when you're calling extsprintf; on the
-	 * other hand, if you did NOT want that (i.e., there's actually a bug
-	 * where the program assumes some variable is non-null and tries to
-	 * print it, which might happen when constructing a packet or file in
-	 * some specific format), then it's better to stop immediately than
-	 * produce bogus output.
-	 *
-	 * However, sometimes the bug is only in the code calling VError, and a
-	 * programmer might prefer to have the error message contain "null" or
-	 * "undefined" rather than have the bug in the error path crash the
-	 * program (making the first bug harder to identify).  For that reason,
-	 * by default VError converts "null" or "undefined" arguments to their
-	 * string representations and passes those to extsprintf.  Programmers
-	 * desiring the strict behavior can use the SError class or pass the
-	 * "strict" option to the VError constructor.
