Verify that, when a file is specified multiple times in a target
list, we still build all of the necessary targets.
This used to cause a target to "disappear" from the DAG when its reference
count dropped below 0, because we were subtracting the duplicated target
mutiple times even though we'd only visit it once. This was particularly
hard to track down because the DAG itself (when printed with --tree=prune,
for example) doesn't show the duplication in the *target* list.
