Ignore self-usage in functions when determing whether it is used about luacheck HOT 4 CLOSED

Good idea, it can be applied to mutually recursive functions, too.

from luacheck.

Implemented on master branch:

Checking test.lua                                 1 warning

    test.lua:1:16: unused recursive function 'foo'

Total: 1 warning / 0 errors in 1 file

Also for mutually recursive functions:

local g

local function f()
   return g()
end

function g()
   return f()
end

Checking test.lua                                 2 warnings

    test.lua:3:16: unused mutually recursive function 'f'
    test.lua:7:10: unused mutually recursive function 'g'

Total: 2 warnings / 0 errors in 1 file

That's really nice that you even take into account mutual recursive functions!

I'm starting to be scared of writing Lua code without luacheck. It prevents so many errors from showing up at runtime and it really helps making sure you're cleaning up any "garbage" while refactoring. Thanks a lot for this tool!

No problem, thanks for ideas! 0.14.0 released.
