docs: Remove stuff from globbing

That `find` example is a bit dated and awkward, and doesn't really fit
the section.

We also don't want to point people to `?` because we want to remove it.

 - ``?`` can match any single character except ``/``. This is deprecated and can be disabled via the ``qmark-noglob`` :ref:`feature flag<featureflags>`, so ``?`` will just be an ordinary character.
 
-Other shells, such as zsh, have a much richer glob syntax, like ``**(.)`` to only match regular files. Fish does not. Instead of reinventing the wheel, use programs like ``find`` to look for files. For example::
-
-    function ff --description 'Like ** but only returns plain files.'
-        # This also ignores .git directories.
-        find . \( -name .git -type d -prune \) -o -type f | \
-            sed -n -e '/^\.\/\.git$/n' -e 's/^\.\///p'
-    end
-
-You would then use it in place of ``**`` like this, ``my_prog (ff)``, to pass only regular files in or below $PWD to ``my_prog``. [#]_

 Wildcard matches are sorted case insensitively. When sorting matches containing numbers, they are naturally sorted, so that the strings '1' '5' and '12' would be sorted like 1, 5, 12.
 
 Hidden files (where the name begins with a dot) are not considered when wildcarding unless the wildcard string has a dot in that place.

 - ``a*`` matches any files beginning with an 'a' in the current directory.

 - ``~/.*`` matches all hidden files (also known as "dotfiles") and directories in your home directory.
