This DLL is only needed to invoke the browser in a "git help" call. By
looking up the only function that we need at runtime, we can avoid the
startup costs of this DLL.
DLL usage can be profiled with Microsoft's Dependency Walker. For example,
a call to "git diff-files" loaded
before: 19 DLLs
after: 9 DLLs
(The results depend on the OS; this is on Windows XP SP3.)
