I've had the problem some month ago (in Namur, Belgium) that someone had 
joined many way making one long railway that was both a tunnel and a bridge. 
I had a hard time splitting it again at the correct nodes (I was lucky that 
at the time mapnik didn't update so frequently and I was able to look where 
the bridges/tunnels were)

potlatch should also have such a warning, as beginners generally start with 
potlatch and are more likely to make such a mistake.
(If it already does ignore this comment, I rarely use potlatch)
