Is the following description more precise?

    The optional second argument OUTPUT-BUFFER, if non-nil,
    says to put the output in some other buffer.
    If OUTPUT-BUFFER is a buffer or buffer name, put the output there
      replacing the old contents of that buffer.
    If OUTPUT-BUFFER is not a buffer and not nil,
      insert output in current buffer.  (This cannot be done
      asynchronously.)  In the latter case, the output is inserted
      after point (leaving mark after it).
