A few changes & fixes of the code compaction dated 2004-03-15:
1) maxlen instead of maxlen-1 (it has been decreased by one for that reason)
2) items[i].elem[j] searched while items[i].elem[j].string is not NULL and not index (nothing would have been found)
3) MNOTE_PENTAX_TAG_ISO_SPEED: value of 100: used to get printed as "100", now it was unknown value -> added to items.elem
  I am afraid 200 would also have the same problem (I don't have any sample file) -> also added to items.elem
4) items.elem[10] -> items.elem[7]: 7 is enough, less static memory & smaller executable
