How to set textwidth when editing command line in vi mode

When I press v in readline's vi command mode, it opens the current command line in my editor (nvim, though I assume this is equally applicable to vim), and executes it on a save.

How can I automatically set textwidth=0 when opening nvim in this way?

As an aside, what is the command mode v feature called? man readline doesn't show any binding for v, so I had some trouble titling this question.
