What exactly is ugly, and why? Is hyphen-french's line ugly, or only the lines
for special languages?

The lua db has to contain information about ibycus or it will be included in the
format. Currently the rule is:
- include in the format if there is no entry in language.dat.lua
- otherwise, do nothing at format-generation time, and at runtime:
- load language is normal
- issue an error if disabled

I disagree. There may be patterns usable with Xetex but not with Luatex, so utf
is not a good category.
Btw, it is easy to implement something specific to xetex using the "databases"
key I added.

This is unrelated IMO, since the current system allows to implement anything
they (german-x team) may want, but for information, we (TL team) will do what
they will tell us to do. They're probably going to generate plain text patterns,
and in the meanwhile we'll probably disable them.

I don't want to add too many fields. Would the comment fiel be OK for this use?
