Documentation of deps gives wrong description in example for limiting depth

[endobson]

Description of the problem / feature request:

https://docs.bazel.build/versions/master/query.html#deps

The deps operator accepts an optional second argument, which is an integer literal specifying an upper bound on the depth of the search. So deps(foo:*, 1) evaluates to all the direct prerequisites of any target in the foo package, and deps(foo:*, 2) further includes the nodes directly reachable from the nodes in deps(foo:*, 1), and so on.

The example in the second sentence is wrong because deps(foo:*, 1) returns the direct prerequistes of any target in the foo package and all the targets in the foo package.

Yes, this is really confusing. Also, is there a way to get just the prerequisites themselves? That'd be a really useful feature.
