## Expected behavior, english is required

When I start SpaceVim with some filename passed to it as arguments via command line. I want SpaceVim skip the fancy startify screen as the documentation startify.txt said.

## The reproduce ways from Vim starting (Required!)

Start SpaceVim from command line. Such as `nvim-qt Sample.txt`.  Then SpaceVim starts with the fancy startify screen opened. I have to type `q` to skip the fancy startify screen.
