I would rephrase the last sentence:

  However, when @code{package-enable-at-startup} is @code{nil}, Emacs
  doesn't initialize packages.  When Emacs is started with one of the
  options @samp{-q}, @samp{-Q}, or @samp{--batch},
  @code{package-enable-at-startup} is @code{nil} by default; to
  initialize packages in that case, explicitly set that variable to a
  non-@code{nil} value (e.g., via the @samp{--eval} option).

The reason is that the additional explicit information about how to
initialize packages in this case is IMO valuable, and also we should
avoid passive tense as much as possible.

Thanks.
