nit: fit statement/expr in the same line instead of hanging (#10267)

The code are wrapped due to us using line-length=79 before, but now some
of the code can easily fit in 88 chars.

The formatter did not change this automatically when we changed line-length,
because of magic trailing commas that gets added when they turn into multiple lines.

Black/ruff wrapping them in parens and splitting them into multiple lines
was making it difficult to read.
