Replying to myself again. Using NSWorkspace instead of NSFileManager
did the trick. It has three other benefits beside updating the trash
icon: you can pass the files as an array, so don't need to move each
one individually; you don't need to set up the path to the user's trash
directory; and it handles the renaming of duplicates automatically. In
my case, this saves about 20 lines of code.

I've yet to discover whether it has a performance hit when moving large
numbers of files.
