How to limit to one window with multiple args?

[Ingo Strüwing]

Hi,

when starting emacs with multiple (file-)arguments, it starts with two
windows (in one frame), buffering the last two files.

Is it possible to configure emacs so that it opens one window only?

Additional question:

Is it possible to configure emacs so that it switches to the buffer of
the first file on startup, not the last one? (ideally reversing the
initial buffer list)

Regards
