There seems to be a consensus [to the extent there ever is, anyway]

I have to admit, I try quite hard not to exceed 78. I don't know why
[never been bitten by badly behaved editors], but something about 79
characters in an 80-char window makes me uncomfortable.

Agreed.

Ah. Yes :-)

Actually, I had a follow-up question about indentation planned. I used
to double-indent, but am now more likely to go with e.g.

>>> if check_something(
...     arg1,
...     arg2,
...     arg3
... ):
...     do_something()

as others have suggested. An alternative would be something like

>>> if check_something(arg1,
...                    arg2,
...                    arg3):
...     do_something()

which I like much less. I have to admit, though, that all the original
options make me feel a little dirty except (#4) "shorter variable
names" [which just makes me feel that I am being overly precious] and
(#6 generalised) "this needs refactoring" [which I would say includes
Steven's #5a].
