clippy +nightly: Uncontroversial adjustments from Nick (!1394) · Merge requests · The Tor Project / Core / Arti

Ian Jackson requested to merge Diziet/arti:clippy-common into main Jul 10, 2023

This is a subset of !1388 (closed) containing precisely the commits I completely agree with, cherry picked.

I'll double check the contents, but after that, since @nickm wrote these commits, I will just set it to merge.
