Right.  It only helps when running terminal or editor settings are
limited to ~80 cols.  And even in those cases, sometimes such code
split across lines needs a lot of gymnastics to not degrade in
readability when compared to a longer line.

We're not (yet?) enforcing PEP 8, so either as Eduardo suggested, or
with no changes LGTM.
