At the moment I am working with:
GNU Emacs 21.3.1 (i586-suse-linux-gnu, X toolkit, Xaw3d scroll
bars) of 2008-05-16 on hammer3
And it is also in this one going wrong.
I tried to add nil:
(how-many "\\w+" (point-min) (point-max) nil)
Nothing is displayed in the echo area (it is not the minibuffer I
learned), but there is also nothing displayed after 'words: ' in the
status bar. So that is not a solution.
