Subject: [PATCH] texlive-fmtutil.*: Adapt to installation/removal of
 texlive-lang*.

texlive-fmtutil.hook: Add hyphenation file patterns to the watch list.
texlive-fmtutil.script: Regenerate language.def and language.dat

FIXME: Although the language.def and language.dat in /etc/... have
a comment that says not to edit by hand and use tlmgr instead,
this could previously be ignored because pacman would leave those
files untouched. Now the hook scripts overwrite them.

A better solution would be to mimic what tlmgr would do to those files.
Presumably tlmgr allows local tweaks somehow.
