What is the purpose of making the heading text optional? Why would you
want to match a sequence of hash marks without any text following it?

Strictly speaking, a markdown heading is allowed to be empty -- see for
example https://spec.commonmark.org/0.29/#example-49. I'm happy to
change it if you think it's more useful to show a previous heading which
contains text than an empty one, though.

I don't know what makes sense, I don't write markdown regularly. A quick
check shows that the sequence of hashmarks appears in the hunk header.
Is that useful? (A genuine question!)
