Somthing seems to be wrong with the patch:

Attached is v2 of the patch. It implements the removal of overlay lines when
mkgmap:set_unconnected_type=none or mkgmap:set_semi_connected_type=none was
found.

I am still not sure what should be done if the tag has a value that gives
another type instead of none.
Assume your style uses
highway=service & service=driveway {set
mkgmap:set_semi_connected_type=0x10806}
highway=service [0x07 road_class=0 road_speed=2 resolution 22 continue]
highway=service & oneway=yes [0x10106 resolution 24]

What would you expect for a semi connected way?
We have 2 lines, the first is changed from 0x07 to 0x10806. It would not
make much sense to change also the 2nd from 0x10106  to 0x10806.
So, for now only the value none has an effect for the overlay line(s).
