As I read it, the doc weighs both > code and comment as "statement". No, comments are not statements (in C). You'd also never even consider interpreting it that way if you knew where that exception comes from (namely that people break long *statements* just to fit under 80 chars, thereby sometimes making the *code* unnecessarily hard to read). > And how on the world that breaking a single word to the next line improves > readability? I fail to get it :/ You got it backwards; you should only go *beyond* 80 chars if it "significantly increases readability".

Checkpatch is just a tool, not the standard, and knowing when it is ok to break the 80 column rule for code requires human judgement. Johan
