[mkgmap-dev] Removing Dead Ends

Hi Recently, an area has become riddled with short highways=footway leading to individual houses ; these are (perhaps correctly) not marked private   as they are drawn from  a residential road. They are basically dead ends. Problem is they  'freeze up' the map on my garmin. I can delete them using the length   <5m tag but that will also remove footways which are short and NOT dead ends. Is there a boolean mkgmap:report_dead_end   I can use? Regards Nick
