[tex-live] Bug#450875: patgen: Does not seem to generate anything useful

[Karl Berry]

    patgen can only read files containing ONLY \patterns{...}

As opposed to what?  I wouldn't expect patgen to parse .tex files.

As far as I can tell from a quick glance at patgen.web, it reads a
hyph-en-ated word list and (optionally) existing patterns (and an
auxiliary "translate" file), and spits out new patterns.
