Comment (by azaozz):

 Looking at the new test in 53668.6.diff, not sure that a good use of the
 `wp_unique_filename` filter. Perhaps having access to each filename that's
 checked for collision may be used in plugins, but may be better to add
 another/specific filter there that should probably just filter `$number`
 and not allow changing the (currently tested) filename?
