Rust-clippy: Truncated message

[fpoli]

I recently got the following message:

warning: use of `unwrap_or` followed by a function call
  --> jni-gen/src/generators/module.rs:17:24

22 |                 match opt_rec_result {

The issue is that the suggested change regarding unwrap_or is not shown.

I'm going to be looking at or_fun_call this coming weekend to implement https://github.com/rust-lang-nursery/rust-clippy/issues/2338. I'll fix this then if the issue is still open.

[oli-obk]

I fear this is something that needs to be fixed in rustc.

[lzutao]

I believed this is fixed.

Yeah, the or_fun_call lint now has a much smaller suggestion span so this should indeed be fixed
