    1.44 +// Alphabetic input of the names of months and the names
    1.45 +// of weekdays requires matching input against a list of names.
    1.46 +// We use a simple generic algorithm to accomplish this.  This
    1.47 +// algorithm is not very efficient, especially for longer lists
    1.48 +// of names, but it probably does not matter for the initial
    1.49 +// implementation and it may never matter, since we do not expect
    1.50 +// this kind of input to be used very often.  The algorithm
    1.51 +// could be improved fairly simply by creating a new list of
    1.52 +// names still in the running at each iteration.  A more sophisticated
    1.53 +// approach would be to build a trie to do the matching.
    1.54 +//
    1.55 +// We compare each character of the input to the corresponding
    1.56 +// character of each name on the list that has not been eliminated,

    1.58 +// matched, or because some character has not been matched.  We
