That is my charitable interpretation, but it's always one or two changes across a module that has hundreds, maybe thousands of lines of code. I'd expect an auto-formatter to be more obvious.
In any case, just looking over your own PR briefly before submitting it catches these quickly. The lack of attention to detail is the part I find more frustrating than the actual unnecessary format changes.
Why would you are about blank lines? Sounds like aborted attempts at a change to me. Then realizing you don’t need them. Seeing them in your PR, and figuring they don’t actually do anything to me.
