Subject: [PATCH] Apply format only if --format is specified

clang-apply-replacements is now applying format even when --format is specified.  This because, methods like createReplacementsForHeaders only takes the Spec.Style and would re-order the headers even when it was not requested. The fix is to set up Spec.Style only if --format is provided.
