It's all over my Lua. Really, it should only be checking the comments. Since most programs that know (roughly) what comments are seem to be either compilers, code line counters or syntax colorers, I'm not sure what accurate-ish tool one could use for this, but it seems a pity either to turn off this check by default, or on the other hand to emit false positives for Python, Lua &c. programs.
I could imagine getting Emacs to provide only comments by loading a file and then scanning its text properties (at least for modes that use a standard face, like comment-face). I'm not sure whether that's ingenious or heinous. -- http://rrt.sc3d.org
