Be careful using setq-default in .emacs. The difference between setq and
setq-default is that if the variable is already bound to a value,
setq-default does nothing. This can cause confusion/problems when you
are working/tweaking your .emacs and you want to re-evaluate things. If
you have your .emacs split into multiple files to make it easier to
manage, it can be even more confusioing as you may have the same value
being set somewhere else and you start ripping out your hair tyring to
work out why your changes are not taking effect. 

This is not to say that setq-default should not be used. To a large
extent its a matter of taste/style. I just wanted to emphasise the
differences between the two.
