odg diff creates weird output

[sveinse]

Using odg diff creates strange output:

$ odg diff tests/od/slave-ds302.json tests/od/slave-emcy.json
odg: 'tests/od/slave-ds302.json' and 'tests/od/slave-emcy.json' differ
Changes:
<< - >> ['description'] value changed from 'Slave with DS-302' to 'Slave with emergency support'
    >>> ['@@"0x1014"  // 4116@@'] only in RIGHT
<<<     ['@@"0x1F20"  // 7968@@'] only in LEFT
<<<     ['@@"0x1F21"  // 7969@@'] only in LEFT
<<<     ['@@"0x1F22"  // 7970@@'] only in LEFT
<<<     ['@@"0x1F50"  // 8016@@'] only in LEFT
<<<     ['@@"0x1F51"  // 8017@@'] only in LEFT
<<<     ['@@"0x1F52"  // 8018@@'] only in LEFT
<<<     ['@@"0x1F53"  // 8019@@'] only in LEFT
<<<     ['@@"0x1F55"  // 8021@@'] only in LEFT

The @@ format is the internal format used for making jsonc comments.
