Fix bad hyphenations for US English
Previously, words like "democrat" and "democrats" were mishyphenated,
although TeX hyphenated them properly. The source of the problem was
in the upstream data, where it incorrectly overweighed hyphenation
exceptions like "democratism" and the added patterns resulted in
mishyphenation of words like "democrat".
Now, we restore the pattern file for US English to the original Knuth
list, and instead add the exception list from TUGboat.
