Let's say I recovered a bunch of swapfiles in quick succession:
gvim -r .swv gvim -r .swu gvim -r .swt
And then cycled through them all a few times before finding that one of them was nonsense. I want to now know which swap file is represented by this buffer of useless contents, so that I may delete it so as not to have known garbage floating around on my hard drive. How can I switch to that buffer/window and then query the name of the swapfile associated with that particular buffer?
