+/* KDE 4 format strings are processed by method
+   KLocalizedStringPrivate::substituteSimple(string,'%',false) in
+   kde4libs-3.93.0.orig/kdecore/localization/klocalizedstring.cpp .
+   A directive
+     - starts with '%',
+     - is followed by a non-zero digit and optionally more digits. All
+       the following digits are eaten up.
+   An unterminated directive ('%' not followed by a digit or at the end) is
+   not an error.
+   %1 denotes the first argument, %2 the second argument, etc.
+   The set of used argument numbers must be of the form {1,...,n} or
+   {1,...,n} \ {m}: one of the supplied arguments may be ignored by the
+   format string. This allows the processing of singular forms (msgstr[0]).
+   Which argument may be skipped, depends on the argument types at runtime;
+   since xgettext cannot extract this info, it is considered unknown here.  */
