PATCH: 3.1.5: ``***'' symlink follow broken

[Geoff Wing <gcw@xxxxxxxxx>]

Heyla,
``***'' recursive globbing with symlink follow has been broken since at
least 3.1.2 (maybe before):

% mkdir 1 2
% ln -s ../2 1/
% echo > 2/foo
% zsh-3.1.5 -fc 'echo 1/***/foo'
zsh: no matches found: 1/***/foo
% zsh-3.1.2 -fc 'echo 1/***/foo'
zsh: no matches found: 1/***/foo
% zsh-3.1.0-test3 -fc 'echo 1/***/foo'
1/2/foo
% zsh-3.0.5 -fc 'echo 1/***/foo'
1/2/foo


This patch is probably suboptimal (possibly wrong) and may encourage someone
to make a real patch.
