Hmm, When `hidden` has been set, I think that should not occurs `E37`.

BTW, `:next` in latest Vim, I get expected behavior. `:prev` is also so.

$ vim -Nu NONE 1 2 -c "set hidden modified" -c next
No error

$ vim -Nu NONE 1 -c "set hidden modified" -c next
E163: There is only one file to edit

$ vim -Nu NONE 1 2 -c next -c "set hidden modified" -c next
E165: Cannot go beyond last file


$ vim -Nu NONE 1 2 -c next -c "set hidden modified" -c prev
No error

$ vim -Nu NONE 1 -c "set hidden modified" -c prev
E163: There is only one file to edit

$ vim -Nu NONE 1 2 -c "set hidden modified" -c prev
E164: Cannot go before first file
