avoid bare except: in stdlib

[iritkatriel]

Bare excepts are best avoided, this issue is to reduce their use in the stdlib. It is not the intention to blindly replace them by except BaseException:, or to religiously purge all of them, but just to review them and avoid where it's feasible to do so.

(see also #125514).
