I should have checked, yes. I did, but I oversaw this. I admit, it's
all my fault (lucky me that I don't know the differences between the
two orthographies well enough).

There have recently been some more changes (for example Hungarian now
includes way more extensive patterns, and Lithuanian and Latvian have
been added, but there's no support for the two languages in ConTeXt
anyway). Just FYI.

(Just out of curiosity - why has { "agr", "hyph-grc", "ancient greek"
} been commented out? My next question to Thomas would be how you
handle those patterns in pdftex, but I won't ask that.)

My fear is that there could be some tiny difference in that
reimplementation of hyphenation algorithm. Most words hyphenate
properly and equally in both engines. This is the first
counter-example that I have seen. But that might be something for Taco
to check.
