lua-5.2.2 

Unfortunately github is also showing the #20679 and #206780 changesets, since this changeset is predicated upon those.  Merging them to master in the correct order will do the right thing though, AFAICT.

I would have liked to add a lua-5.2.pc file to point to the debian-inspired `include/lua-5.2` et. al. but I don't know the idiomatic way to create a whole new file in a Formula (brew seems to ignore patches that create files :( )- when I get an answer on the homebrew ML, I'll submit another pull-request to add one.
