\@idxwrite explicitly calls \ignorespaces for silent macros at the end
of processing, so the following spaces were meant to be ignored.

I would bet this is how \sidx was meant to be used.  Arguably,
indexing "points" make more sense in front of the indexed term rather
than after (although the non-silent command do place it after the
term).  But more importantly, this allows something like the

  \sidx{polar bear}
  \sidx{Ursus maritimus}
  Polar bears live only in the northern Arctic.

without having to worry about adding `%' after each \sidx{...}.
