Done — the account-level setting is what was wrong, and it is fixed now.

`Settings → Emails`: the primary address is `balcihkutsi at gmail.com` and *"Keep my email addresses private"* is off, so the squashed merge commit will be authored with that address instead of the noreply. The branch commit `69dd6b63f` was already authored `balcihkutsi at gmail.com` (visible under **Commits**), so the branch author and the squash author now agree.

Apologies for the two round trips — I had fixed the commit author and assumed that covered it, but it is the account-level flag that decides the author of the squashed commit.

Nothing else changed: still the same two lines in `HowToSubmitABug.rst:81` and `PdbStream.rst:149`.
