The comment is needless noise that the reader must check for correctness and then determine whether it or the code is the intended behaviour when they differ. The same is unfortunately true of many comments. BTW, you've probably a bug in your regexp because you like to needlessly and wrongly escape a dot without knowing the regexp syntax you're using. Assuming you don't intend $ grep -Eo '[\.]' <<<\\ \ $ that is. :-) (curl's -s should be accompanied by -S IMHO, and it's brain-damaged in not having that behaviour under the one option.)
