"cabal list-bin" should list all available targets on failure

[mouse07410]

Describe the bug
cabal list-bin returns an error instead of listing all of the available binaries.

To Reproduce
Steps to reproduce the behavior:

$ cabal list-bin

Expected behavior
Similarly to ls, I'd expect to see all the binaries.

E.g., ls <file> lists one specified file, but ls lists the entire contents of the current directory.

Thanks. Isn't this fixed already, though? Or at least a PR or ticket made?

Hmm, never mind, I'm probably mixing it up with a similar problem.
