I suggest to omit the concrete examples.
I would prefer the explicit wording for the support of (Unicode) ellipses
also in the shown commit titles.

Will the document =E2=80=9Csubmitting-patches.rst=E2=80=9D need a correspo=
nding adjustment?

Would we like to tolerate such quotation character alternatives?

How do you think about to tolerate extra white-space characters around
the commit identifier?

I find that such an example should trigger further software development co=
nsiderations
for a safe data format description.

I guess that the clarification is still evolving also around this aspect.
