This bug's Component field is assigned to TShark, but more precisely it is
found in the Wiretap library and probably only affects Editcap.

The following is the abridged results of invoking the command line "editcap -T"
to output a list of encapsulation types:

    ...
    bluetooth-h4 - Bluetooth H4
    ...
    bluetooth-h4 - Bluetooth H4 with linux header
    ....

As you can see, there are two similar yet distinct encapsulation types that
both use the abbreviation "bluetooth-h4". Thus, invoking the command line
"editcap -T bluetooth-h4" is ambiguous (although the linear abbreviation lookup
routine always chooses the first occurrance).
