I guess you're right, it should be applied to the pit symbol.
My first thought was, that a pit symbol should always be a closed line. 
But as the symbol is the same, a single name makes it simpler.

I'm checking this with people who were involved in the creation of the 
standard and use it more frequently than I do...

For the symbol I agree, yet I think the depth label should be placed 
manually for a nice position.

Yes, I wasn't happy with the '+' in the middle of the chimney anyway...

ok, I'm not sure wheter I'll get the way arguments are passed to 
metapost, but we'll see...

Thanks for the good suggestions
