We like to have one semantic change per commit. Therefore, if you are
fixing indentation in a code that's unrelated (i.e. you are fixing
indentation in a function you are not touching) then that's considered
as another semantic change.

What I was aiming at is that new code should be indented well from the
beginning. That's obviously one semantic change and as such should be in
one patch (i.e. new code that's well formatted).

Have I answered your question or did I misunderstand?
