Zero values are already tested (the previous version of the code printed a hard-coded zero here -- mainly so I can confirm it works by piping the data to dwarfdump).

The way I think of this is that the first test is for the fixed components of the header, while the file/dir forms are tested in the next test (below). It's true that this doesn't check various endianness/address size versions, but I didn't find that particularly interesting to test as all of the values here are endian-independent (either 1-byte fields or ULEBs).

LMK what you think about that.
