To be honest, I might have misunderstood him. I haven't looked more into
this after my mail. Before posing my question, I created a document with
this word, Then added things words before "tillåta" until it reached the
margin. Groff refused to hyphenate it, so (since this is a fairly common
word -- meaning "to allow") it is most likely that he have added patterns
disallowing erroneous hyphenation. He says in the changelog:

% 1991-11-01: Added another some 6200 compound words, all of which were
%             incorrectly hyphenated by the old patterns.

Before the actual patterns, there is an interesting paragraph (see below).
I removed that before copying the thing to ../groff/1.18/tmac/hyphen.se,
supposing that this wasn't really Swedish but Klingon (possibly
uuencoded).
