This is a list of strings to be shown before everything else. Every string
will be written on its own line, hence you can use empty strings for blank
lines.
Define your own header.
Static example:~
>
let g:startify_custom_header = ['line 1', '', 'line 3']
<
Static example #2:~
This option takes a `list of strings`, whereas each string will be put on its
own line. If it is a simple `string`, it should evaluate to a list of strings.
Helper functions:~
startify#fortune#quote() random quote
startify#fortune#boxed(...) random quote in a box
startify#fortune#cowsay(...) random quote in a box + cow
The last two functions optionally take a quote in the list of strings format.
They also return a list of strings, suitable for this option.
Example #1:~

let g:startify_custom_header = [
\ ' ________ __ __ ',

If you go for a dynamic header, you might find the following functions useful:
Example #3:~
startify#fortune#quote() raw random quote
startify#fortune#boxed(...) opt list or formatted random quote in a box
startify#fortune#cowsay() formatted random quote in a box + cow
Try them like this:
>
:echo join(startify#fortune#cowsay(), "\n")

Let's assume you like the default boxed random quote, but not the ASCII art
cow. You'd rather have another small ASCII art come before the quote. No
problem!
