The important stuff is in the src directory. The repository was pretty
messy. I've cleaned it up a bit and added a patch file, which shows
the changes. To use the patch, I unpack a fresh copy of Lua 5.3.5 and
invoke these commands in the top directory:

patch -p1 < utf8_identifiers.patch
make linux 'MYCFLAGS=-D ALLOW_UTF8_IDENTIFIERS'

There are two Lua files, which you don't need: the tests, and
make_data.lua, which generates the Unicode data from
DerivedCoreProperties.txt in the Unicode Character Database and
modifies src/unicodeid_template.h to create src/unicodeid.h.
