[luatex] Strange hyphenation

[Manuel Pégourié-Gonnard]

Hi,

I'm aware that the problem of activating Italian patterns on Taco's machine is
solved, but anyway, just for the record:

This is incorrect for two reasons:

1. language.dat.lua is not generated from language.dat: both are generated from
the information in texlive.tlpdb & local files language-local.dat(.lua). See the
"generate" section in tlmgr's manual for details. Also, it is strongly
recommended not to edit language.dat manually, as stated in the comments:

% DO NOT EDIT THIS FILE (language.dat)! It is generated by tlmgr.

2. Lualatex doesn't dump patterns themselves in the format any more, but it
still stores the list of languages available for babel. So, formats still need
to be rebuild after changing this list. This limitation will be removed in the
future, but I'm unlikely to act on it before a few months.

Manuel.
