Alignment is unreasonable.  I just think this example should look like
other examples of this kind - one space, before and after dot - even
if from perspective of code it is correct to put more than one space.

If I'm the only one with this "problem", i.e. no one else will add
anything in few(?) days, then you can close this bug as "wontfix"
or "not a bug" or something.
