Revert "; Fix coding style in just installed change"

This reverts commit 229f0b8dd3b92827b6e0c6fc105508e8b80858f5.
This is part of removing the recently-added feature whereby
certain non-nil values of 'header-line-format' could signal
that the header line shall not be displayed.  The feature is
being reverted because its advantages are very minor, whereas
the complications it causes are serious.
