Can we put a comment referencing the issue next to the relevant input value to loffset?

go ahead and inlinethese (add an overall comment if you would)
cc @jbrockmendel we should define scalar function helpers for this as we repeat lots of this in ops....

if you want to use hypothesis would be great here :> (can be followup, not sure how easy)

There are no many examples in pandas codebase how to use hypothesis. Furthermore, I know only 4 cases which need to test: timedelta(minutes=1), '1min', Minute(1), np.timedelta64(1, 'm'). Did I miss something?
