tab completion ignores baz.log file contrary to documentation

[Joe Bayes]

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 20.7.1 (i386-redhat-linux-gnu, X toolkit)
 of Fri Mar 16 2001 on porky.devel.redhat.com
configured using `configure  --mandir=/usr/share/man --infodir=/usr/share/info 
--prefix=/usr --libexecdir=/usr/lib --sharedstatedir=/var --with-gcc --with-pop 
--with-x-toolkit i386-redhat-linux-gnu'

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

Summary: emacs' "minibuffer-complete" function ignores the file
"baz.log". "C-h f" doesn't say anything about it ignoring certain
files. Either the command should not ignore that file, or the
documentation should be changed to reflect the current behavior.

To reproduce the bug:

spoo:~$ mkdir foo
spoo:~$ touch foo/bar
spoo:~$ touch foo/baz.log
spoo:~$ emacs -q -nw
C-x C-f f o o / <TAB>

emacs completes the filename "foo/bar", but according to the
documentation it should only complete "foo/ba", and display the list
of possible completions, "bar baz.log".
