This should be discussed, indeed.

AFAIK, this is not correct; `.' is not restricted to non-categorized
words.  For example, we have

  An-den.ken

[For non-wortliste users: a hyphenation point is `near' if the
 distance is smaller than three characters.]

As you correctly write, some of the full stops could be avoided.
However, in some cases `=.' could be helpful for clarity.

As mentioned in other mails `.' is essentially a shorthand for `-.'.

Hmm, good examples – better than the Dutch ones :-) But patgen can't
handle this.  What about libhyphen?
