As noted here¹ rust-clap-2 is listed as both a dependency and a
build-dependency. For the sake of completeness, there are also packages
which require the same crate+version for cargo-dev-input and a looser
version requirement for cargo-input. It seems worthwhile to deduplicate
the cargo-inputs, since it's a combination of 'dependencies' and 'build
dependencies', but I'm not sure about removing duplicates when they
appear in both cargo-inputs and cargo-development-inputs.
