Info-mode: case-fold-search is nil, Info-menu doesn't work

[Jeff Sheinberg]

This bug report will be sent to the Free Software Foundation,
 not to your local site managers!!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

In GNU Emacs 20.7.2 (i386-debian-linux-gnu, X toolkit)
 of Tue Jul 25 2000 on raven
configured using `configure  i386-debian-linux-gnu --prefix=/usr 
--sharedstatedir=/var/lib --libexecdir=/usr/lib --localstatedir=/var/lib 
--infodir=/usr/share/info --with-pop=yes --with-x=yes --with-x-toolkit=yes'

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

    $ emacs -no-init-file
    C-h i
    M-x toggle-case-fold-search
    m
    "No menu in this node"

in order to fix this, all of the menu search commands need to
(locally, in a let block) set case-fold-search to t, or else
change the regexp they are using to search with.

The Info-search command does seem to obey case-fold-search
properly, it's just that the Info-menu command stops working when
case-fold-search is set to nil.
