I think reasonable people can disagree about what is and is not a
problem, is or is not an improvement, or even misunderstand eachother
entirely.  Sometimes patience and additional explanations are the way to
move forward.

In this case, I agree with Lars that the company-dabbrev docstring is
consistent with Emacs' usual way of writing docstrings.  I don't
actually see a clear way to improve the one docstring in isolation
without it becoming inconsistent with the rest of Emacs.  And so, I
would expect any improvement here to involve some discussion, since the
path forward isn't obvious.
