Crossing wires on circuit diagrams - how to show?

[Chris G <cl isbd net>]

How do people here show crossing wires on circuit diagrams in dia?

Do you simply use the convention that a pair of wires crossing each
other on the diagram are not connected and junctions shown as a T are
connected?

I prefer to show a little 'loop' where one wire crosses another and have
tried a small arc to do this but it's clumsy for a couple of reasons -
the arc doesn't have connection points on the ends and, if you add
connection points I can't see how to make them transparent.

Even if you don't use the 'loop' convention you then really need a way
to offset connections where you really want crossing wires to be joined.
