[binary builders] luatex beta-0.89.2

New beta-0.89.2 is on the svn server. We already know that there are some issues---the broken luajittex on solaris/bsd, but also \mathchar loadfile and some metapost things---and we have already planned another beta for the next week. On the other side, the lost minus sign on pdf backend is a critical fix, so it's better to have the best luatex available as soon as possibile. -- luigi
