I have seen a wide variety of -1'ing (and in many cases approving) 
patches for minor spelling or grammatical errors and think we need a 
policy about this. Given the large number of contributors for whom 
English is not their native language, I would be in favor of rejecting 
spelling errors in variable or method names but being more lenient in 
comments, commit messages, READMEs, etc. What do you all think?
