{man,lispref}/display.texi

[Luc Teirlinck]

Very recent changes to {man,lispref}/display.texi broke bootstrapping.
I made minimal changes to make bootstrapping work again.  It seems
obvious that further changes are needed to lispref/display.texi, but I
do not have the time to look at it in detail now.  I may do so later,
but hopefully somebody else will do so first.  At least bootstrapping
works again.

Sincerely,

Luc.
