heh - don't spend too much time on it! A little while ago I had a similar
problem, where if the arrow went to the centre of a node, the node covered
its head. The output was svg so my first workaround was to define the arrow
as two lines, with the head at the end of the first one, so it appeared in
the middle of the arc [1]. This made for wordy svg though, so later I spent
ages trying to do the sums to get the arrow to touch the side of the
rectangle. The nearest I got has the arrow ending in mid-air [the svg from
2], and unfortunately other work has meant it'll have to stay there for the
time being...
