Maintain functional continuity with Z

[sarahsturgeon]

When you call z with no arguments, it just prints the frecency list.

When you call v with no arguments, you're presented with a prompt to enter a choice.
This isn't very useful because most vim users will have many files in their recently accessed list, and after they're presented with the list they can just re-run v with the filename they want.

I think v on its own should open the most recently edited file.

v -l should do what you're asking (the equivalent of z or z -l)
