Thanks! I finally tested this, and it looked OK with my fabricated data 
and style file patch, which did { add fixme=yes } to some nodes.

I did not implement the dead-end checks. I believe it was Mark Burton, 
who no longer is active in the project. Can you draw ASCII art of the 
situation? For example, using the following legend:

= means two-way road
> means one-way road
| means dead-end

The cases |==== or ====| should not emit any warning; these should be 
common for highway=residential and highway=service etc.

====>>>>>| should emit a warning 'goes nowhere'
====<<<<<| should emit a warning 'comes from nowhere'
====>>>>>==== no warning
====<<<<<==== no warning

This is my reasoning; I did not test the actual behaviour. Which case 
did you have in mind?
