AFAIK this is a side effect of `global-font-lock-mode'. The global mode (on by default) enables font-lock-mode in any buffer, while the default value of `font-lock-mode' remains nil. But OTOH the font-lock-mode related display functions kick in only when certain variables are not nil (like `font-lock-keywords'). Michael.
