Lines 145-152 are a copy of lines 133-142, except that |n| and |buf|
don't need to be updated because they won't be used again in the rest
of the function. Therefore it is just the indentation of line 152 that
is wrong.

Similarly, lines 178-184 are a copy of lines 167-175 except that |n| and
|buf| don't need to be updated.
