-  \fn QString QString::arg(const QString& a1, const QString& a2) const
-  \overload arg()
-
-  This is the same as \c {str.arg(a1).arg(a2)}, except that the
-  strings \a a1 and \a a2 are replaced in one pass. This can make a
-  difference if \a a1 contains e.g. \c{%1}:
-
-  \snippet qstring/main.cpp 13
-
-  A similar problem occurs when the numbered place markers are not
-  white space separated:
-
-  \snippet qstring/main.cpp 12
-  \snippet qstring/main.cpp 97
-
-  Let's look at the substitutions:
-  \list
-  \li First, \c Hello replaces \c {%1} so the string becomes \c {"Hello%3%2"}.
-  \li Then, \c 20 replaces \c {%2} so the string becomes \c {"Hello%320"}.
-  \li Since the maximum numbered place marker value is 99, \c 50 replaces \c {%32}.
-  \endlist
-  Thus the string finally becomes \c {"Hello500"}.
-
-  In such cases, the following yields the expected results:
-
-  \snippet qstring/main.cpp 12
-  \snippet qstring/main.cpp 98
