Which part(s) of the documentation caused this interpretation?  AFAIK,
the truth is that the output is inserted at point (i.e. point is left
_before_ the output), unless indicated otherwise by
shell-command-dont-erase-buffer.  So if something we say tricks you to
think otherwise, we need to fix that text.

Thanks.
