Configure splash screen

[Krzysztof Bieniasz]

Hi all!

I have an unusual need for splash screen customization. I find it awfully 
annoying when I open an existing file and the splash screen opens in 
another window. I do know I can prevent that with (setq inhibit-splash-
screen t). So what's the problem, you might ask? You see, I kinda like 
the splash screen itself. Is there any simple customization to enable it 
when starting Emacs without a specified file and to disable it when 
running Emacs on a file? Or rather to have it run in a hidden buffer in 
the latter case?
