Another example, one of many from @vivo.com, where you touch one line
and leave everything else not modified.

Are you going to send 5 different patches - one per each line? You
generate tremendous amount of work for reviewers to handle this.

Since ~2 weeks there is tremendous amount of trivial patches coming from
vivo.com. I identified at least 6 buggy, where the contributor did not
understand the code. Not sure about intention, but I advise extra
carefulness when dealing with these "trivial" improvements (because we
tend to apply things which look trivial).
