Try to fix bug 25999 , patch for dlls/mshtml/navigate.c

[Qian Hong]

Hi Jacek,

It seems http://bugs.winehq.org/show_bug.cgi?id=25999  has no update
from Wine developers,
my friend Zhuo Wei has write a patch for it, tests in
dlls/mshtml/tests are run on Wine,
( according to http://www.winehq.org/docs/winedev-guide/testing-wine
), every test passes
successfully, could you help to review it ?

Thanks a lot!
