bug#1113: slash screen covers the *Messages* buffer when errors are present in .emacs

[Dan Nicolaescu]

Create a bad .emacs:

echo ")" > ~/.emacs

emacs&

Emacs starts up, it shows the *Messages* buffer that says that there are
errors in .emacs, but the splash screens covers it before the user has
time to read the information.

The splash screen should not be displayed at all in this case, the user
has to have a chance to read the text in *Messages*.
