Subject: Info-use-header-line nil => no navigation via header buttons (what was the header line)

I'm using GNU Emacs 21.1.1 (i366-msvc-nt-4.0.1381) of 2001-10-22 on buffy.

1. In virgin Emacs (-q), load-library info.
2. Set Info-use-header-line to nil.
3. Start Info: C-h i.
4. Clicking on the header navigation buttons "Next" etc. doesn't do
anything. The mouseover mouse-face and help ("Go to...") string are
displayed, but no navigation takes place.

[These are the navigation buttons that would appear in the unscrollable
header line if Info-use-header-line were non-nil. They are what you used to
see/use in previous versions of Emacs. When Info-use-header-line is nil,
this line of buttons appears only at the beginning of the buffer (it scrolls
with the buffer).]

Also, setting the user option Info-use-header-line should be possible after
Info is displayed, and it should change the display to reflect the user's
request. At the least, there should be a redisplay command/function to take
into effect the change in value of Info-use-header-line. Currently, the user
must exit Info and reenter it.
