Hi Steve,

yes, NodDisplay from r338 doesn't show any error messages for
img files created with mkgmap.
It still shows lots of them for my Garmin img file.
I think one of the reasons is this ugly zero byte that follows the
table C. As you mentioned in the commit, this is not correct and
I think my Garmin map contains data that is misinterpreted
when this zero byte is skipped.

Attached is a small excerpt of my output file containing the
header and the first lines of NOD1.
