Title: Allow filename with extension in find_cmd in Windows.

closes gh-3316 (hopefully)

According to [documentation here](http://docs.activestate.com/activepython/2.4/pywin32/win32api__SearchPath_meth.html), SearchPath takes an optional third parameter for the extension, which is only added if the filename doesn't have an extension.

Should be tested by someone on Windows.
