part of the +wininet,+relay log

I noticed that the streaming installer of WoW stopped working with 1.1.13, it
complains about not being able to download any information from the net.
Bisecting showed the following commit is causing the problem:

12931062fbf5387cfcb0bdb65a110c503728bd6b is first bad commit
commit 12931062fbf5387cfcb0bdb65a110c503728bd6b

wininet: Make sure that we have data buffered before sending
INTERNET_STATUS_REQUEST_COMPLETE notification.

The attached log (+wininet,+relay) shows relevant (i hope) parts of the log,
the problem seems to happen somewhere inbetween. The message box in the last
line is the one showing the error message before the installer quits.

Affected installer can be downloaded at the link provided in the URL field.
