** Misc
*** Vim Scrolloff
This makes scrolling gradual rather than by half page. I find that the
half page scroll really makes me lose where I am in the file so here
I make sure to scroll one line at a time. In addition I want to keep
what I'm working on centered so I start scrolling when the cursor is
10 lines away from the margin.
This behaviour in general emulates the =scrolloff= option in vim.
