Does anyone know how OS-X and/or the Finder treats files without an extension? If I have a plain text file without an extension, then changing the program that opens txt files will make it change for plain text files without an extension. But if I have an RTF file without an extension, it doesn't open with the default TXT application, nor with the default RTF application, but instead always seems to open in TextEdit. I suspect (but have no proof) that in the no extension/file type/ creator combination, LaunchServices falls back to the unix 'file' command to work out the type of file based on its contents and decides what app to launch.
