Note that an extraneous ";" as here is basically an empty R (or
S language) statement.
So it is 100% correct that the indentation behaves as it does.
Changing it would be wrong.

and really I just don't get it why some people want to use a
wrong syntax for R, or do like to add empty statements at the
end of almost every line of R code ....
It *will* make your code somewhat slower, maybe not noticably, ...
