I had always intended that mkgmap would be able to fix up the family
and product id when using a TYP file.

This is already done for a text typ file, the command line options
override whatever is in the text file.

Here attached is a patch that implements patching in the correct family and
product id's before adding to the gmapsupp.img.

I don't want to patch the original file directly, so a copy is made
beginning with the letter 'x' which is copied into the gmapsupp.
This file automatically gets used if you are creating a nsis windows
install file too.

Yes, it always worked with a text file, and that is the
way I would recommend it be used if possible.
