-/* 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.

-// __get_formatted_time reads input that is assumed to be formatted
-// according to the rules for the C strftime function (C standard,
-// 7.12.3.5). This function is used to implement the do_get_time
-// and do_get_date virtual functions, which depend on the locale
-// 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
-// the appopriate name table or by doing a __get_integer_nogroup.
-//
-// '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.
