Terminal output

In Audacity, open an audio file and then go to file -> export. On this file
dialog, any selection from the "files of type" drop-down list will (apparently)
be treated as "all files", which leads to two minor annoyances:

1. DLLs and other unrelated file types will be listed while browsing for a
destination folder. (This doesn't happen immediately when the dialog opens,
only after changing the destination directory and/or file type.)
2. If the file extension isn't specified manually, Audacity will try to append
".*" to the end of the file name and then warn that this is a non-standard
extension for this type of file.
