+/* ########## printf core implementation with some extensions ########## */
+/*
+ * How to use the extensions:
+ * - put ' or " in the flags field to quote a string with this char and
+ * escape special characters (only available, if PRINT_QUOTES is defined)
+ * - put \\ in the flags field to quote special characters and leading and
+ * trailing spaces (only available, if PRINT_QUOTES is defined)
+ * - arrays (only available, if PRINT_ARRAYS is defined)
+ * - the array modifier [ comes after the maximal field width specifier
+ * - the array length can be specified literally, with the '*' modifier
+ * (in which case an argument is expected) or will be automatically
+ * determined (stop values are -1 for ints and 0 for strings)
+ * - these modifiers expect their argument to be an in-line string quoted
+ * with an arbitrary character:
+ * - (, ) -> array pre-/suf-fix; default ""
+ * - <, > -> element pre-/suf-fix; default ""
+ * - | -> element separator; default " "
+ * - these modifiers expect no argument:
+ * - : -> print '<number of elements>: ' before an array
+ * - , -> short for |','
+ * - { -> short for ('{')' }'<' '|''
+ * - the pointer to the array is the last argument to the format
+ * - the %m conversion from syslog() is supported
