The "file" command with the -i option is supposed to output a MIME
type. However, the magic.mime file has a small typo which causes it to
add extraneous output ("audio/unknown") for WAV and AVI files.

    $ file -ib Zoolander.avi 
    audio/unknown	 video/x-msvideo
    $ file -ib bodhisattva.wav | vis -t
    audio/unknown\011 audio/x-wav\011

Note that in addition to the extraneous "audio/unknown", the MIME type
for WAV files also has a superfluous TAB at the end.


Edit /usr/share/misc/magic.mime. Delete the phrase "audio/unknown"
from line 91. Delete the tab at the end of line 93. Rerun "magic -iC".
