have asked you this in the past, and previously you'd said that
it was because you switched news readers.  That's fine, but that
was a year ago or more.

Actually, Thunderbird made the change to how the "Reply" button works
sometime around April 2021, and I'm still making the mistake of hitting
it when I should hit "Followup". At my age it's hard to change a habit
acquired over a couple of decades of posting to usenet; I'm doing my
best to change it, and still failing frequently.

Three and a half years is a long time to learn how to use a tool
competently.

I'm unlikely to deliberately send you e-mail, so you can easily avoid
the aggravation of dealing with my accidental e-mails by simply
kill-filing me.

Please don't put the onus to deal with your mistakes on me.

b) What you are referring to, from the section on Additive
Operators (6.5.7 in n3220; 6.5.6 in C99) is in reference to
pointer arithmetic; the statement that I was replying to was a
general statement about pointers, independent of issues of
pointer arithmetic.  That is, it is not the case that, "each
pointer in C points to an array".  The above example, to which
you replied, is a counterpoint to the general statement.

I disagree. It is not independent, because there's nothing you can do
with pointer itself that has either it's value or it's validity
dependent upon whether that pointer points at a single object or the
first element of an array of length one.

You can indirect it without doing arithmetic on it.  This isn't
a particularly interesting topic, however.  The point was that
the OP's statement was factually incorrect.
