strange w3m completion

[d+zsh@xxxxxx]

Hi,

I got strange w3m completion in zsh 4.3.6-4 (Debian).

For example,

----- ~/.zshrc -----
autoload -U compinit
compinit
--------------------

----- ~/.w3m/history -----
http://example.com/index.html
http://example.com/file.html
--------------------------

behavior 1) 
% w3m http://example.com

If I hit tab, then I get below result.

% w3m http://example.com/.html

and I hit tab in a row,
but I cannot get another results.

behavior 2)
% w3m http://example.com/

If I hit tab, then I get below result.

% w3m http://example.com/
http://example.com/file.html   http://example.com/index.html

Behavior 1) is not intentional and I am inconvenienced.
So, I modified zsh/functions/Completion/Unix/_w3m,
It makes behavior 1) gets the same result that behavior 2)'s.

But I do not know whether it is correct approarch,
it is feared that it makes a bad side effect.
Please let me know better approach if exists.
