I see. I wonder if it would even be possible to merge common dependency
subtrees in this form of ascii report. 

However, if the script supported graphviz (.dot) output it would be
perhaps feasible. The merging perhaps could even happen automatically
within graphviz. Please look at the sample graphics I've prepared with
graphviz: http://admin.sibptus.ru/~vas/t.png I did not do any special
common dependency processing, graphviz merged the "expat" dependencies
for me.

Anyway, even in this form the utility could be useful to me, thank you
for pointing it out to me.
