Makes it so windows opened from links in Windows Live Messenger cause the window to appear instead of being invisible.
The discovery is that Windows enforces that you call ShowWindow with the value of STARTUPINFO's wShowWindow field first before calling it with any other value, otherwise all subsequent calls are ignored. I used to have code that flattened the return value of a function into something that would ensure the window is visible, but what I actually needed to do was show the window twice in this case. Ick.
TEST=Have someone send you a link in a Windows Live Messenger window, click it without Chrome running (Chrome must be default browser), and a Chrome window should appear, visible, loading the link.
Also try running chrome.exe from bash to make sure that still works.
