Comment (by blobfolio):

 Worked with @btolman to test the patch under Windows and Multi-Site; FINFO
 /MIME-handling worked as expected! Woo!

 The latest version (4) of the patch integrates additional validation post-
 FINFO, re-checking the file information against the list of allowed MIMEs.
 This probably won't result in a change of heart very often, but is
 preferable to allowing everything through (or denying everything as 4.7.1
 accidentally does).

 If anyone else has had a chance to test, please post feedback. Let's get
 this bug fixed! Thanks!
