len_zero: also handle .len() >= 1

[matthiaskrgr]

Since .len() should return unsigned values in most cases, I think we can treat .len() >= 1 the same as .len() != 0 or am I missing something?

if String::from("hello").len() >= 1 {}

does not trigger a warning currently.

good idea!

return unsigned values in most cases,

I think our != 0 check whitelists types that guarantee usize

Can I try to work on this?

All yours!

@oli-obk thank you.

ls it oké if the commits are based on v0.0.195? Rebasing to v0.0.196, with the nightly version mentioned in the changelog, gives me build errors.

I reinstalled rustup, rustc, cargo, all of it and it compiles fine now on my end.
Thank you for the help matthias.

Thank you! :D
I'm closing the ticket, not sure why it was left open.
