mdoc for the man page

[somercet]

First off: I love nnn(1). The batch rename capability is amazing, and I love the "tabbed" context pages that make it easy to select and move files.

Second, I saw the man page is written in mdoc. I love mdoc, but I see a lot of extra formatting commands that mdoc, a purely semantic macro language, shouldn't have. I rewrote the page and have attached it below. Now, my conversion is not complete, nor do I think it is 100% "good mdoc," so if you think you'd like to see a more finished nnn.1 file, please tell me the things you don't like (pointedly, but politely please) below and I will try to fix them.

I hope a more correct mdoc page will look better on websites like man.archlinux.org.

Again, thanks for nnn(1)!
