+/* Matching input against a list of names
+
+ * Alphabetic input of the names of months and the names
+ * of weekdays requires matching input against a list of names.
+ * We use a simple generic algorithm to accomplish this. This
+ * algorithm is not very efficient, especially for longer lists
+ * of names, but it probably does not matter for the initial
+ * implementation and it may never matter, since we do not expect
+ * this kind of input to be used very often. The algorithm
+ * could be improved fairly simply by creating a new list of
+ * names still in the running at each iteration. A more sophisticated
+ * approach would be to build a tree to do the matching.
+ *
+ * We compare each character of the input to the corresponding
+ * character of each name on the list that has not been eliminated,
+ * either because every character in the name has already been
+ * matched, or because some character has not been matched. We
+ * continue only as long as there are some names that have not been
+ * eliminated.
+
+ * We do not really need a random access iterator (a forward iterator
+ * would do), but the extra generality makes the notation clumsier,
+ * and we don't really need it.
+
+ * We can recognize a failed match by the fact that the return value
+ * will be __name_end.

+// specifications for the time and day formats respectively.
+// Note the catchall default case, intended mainly for the '%Z'
+// format designator, which does not make sense here since the
+// representation of timezones is not part of the locale.
+//
+// The case branches are implemented either by doing a match using

+//
+// 'y' format is assumed to mean that the input represents years
+// since 1900. That is, 2002 should be represented as 102. There
+// is no century-guessing.
+//
+// The match is successful if and only if the second component of the
+// return value is format_end.
+
+// Note that the antepenultimate parameter is being used only to determine
+// the correct overloading for the calls to __get_integer_nogroup.
