[#934] enters new exceptions.

[#935] Enter as many hyphenation exceptions as are listed, until coming to a right brace; then return

[#937] Append a new letter or hyphen.

[#939] Enter a hyphenation exception

[#940] Insert the pair (s, p) into the exception table.

[#941] If the string hyph word [h] is less than or equal to s, interchange (hyph word [h], hyph list[h]) with (s, p)
