I believe that you're correct.

Note also that, AFAIR, Metalua fails on that as well, so, if just to
be more compatible, don't use invalid escape sequences in your code.

Also, I find this LJ2 feature really useful to catch bogus PCRE-isms
in Lua string patterns — caught more than one bug this way.
