So is "rewrite_by_lua" also evil?

I've just fixed this issue in ngx_lua v0.3.1rc13.

Now running "rewrite a b;" and "rewrite a b last;" will cause
rewrite_by_lua and rewrite_by_lua_file (as well as others) to skip
completely.

But please note that, only location rematch (or location re-lookup)
triggered by ngx_rewrite's "rewrite" directive (or anything else) will
skip rewrite phase Lua code. It has nothing to do with rewrite
directive's "last" modifier. So "rewrite a b break" will not skip
rewrite-phase Lua handlers just because no location re-lookup will
follow it.

The location rematch (or re-lookup) behavior of the "rewrite"
directive is kinda like internal redirection, but not the same.

BTW, ngx_openresty 1.0.8.9 devel release already includes this version
of ngx_lua :)
