[mkgmap-dev] mdr5 when no streets (mdr20)

Mon Apr 15 17:38:21 BST 2019

Hi

Another problem discovered when investigating indexes.

If you have a map with cities but no streets, MDR5 sets the flag that
indicates MDR20 indexes are present, and writes an erroneous byte after
each record.

Attached patch fixes and adds some more flag documentation.
