According to the style guide:

Note that when the code wraps in this example, both of the && logical AND operators are at the end of the line. This is more common in Google code, though wrapping all operators at the beginning of the line is also allowed.

I saw examples of both having them at the end as well as in the beginning and in some cases, such as macros, a mixture of both in the same expression.

I prefer keeping the operators at the end because to me it is easier to read with the terms lined up, especially in cases where there are several nested expressions.

Rebased on master to see if the build issue goes away. It looked like a luarocks issue.

@davidzchen I'm removing hangul input in the next hour ( #317 ) can you replay this commit after its merged ?

Not a problem. I have replayed my commit on master.

Merged, thanks
