[mkgmap-dev] Style function is_connected ?

Hi Thorsten,

yes, what else should happen? According to the OSM data there is no wait
out,
or do I miss something? Would the device search another road which is close?

Besides that, the question is where you want to stop. If two ways are
connected to each other, but
not to any other road, should they be routable? Three, four... ? I am not
sure if we already have an algo that finds such independent networks, but
it's a standard problem in graph theory and it can be solved in
an acceptable run time.
