Short backtrace

[thewh1teagle]

I have large codebase which uses anyhow::{Result, Context, bail} a lot,
and the errors don't tell much. No filename/line numbers at all.
Using RUST_BACKTRACE=1 is not convenient.

I found #22 but it will require many changes to add it everywhere.
Is there an elegant way to get short backtrace when error occur, just like we get it with unwrap()?

Example:

use anyhow::{Result, bail};

fn main() -> Result<()>  {
    job()
}

fn job() -> Result<()> {
    bail!("error in job")
}

cargo run
Error: error in job

Imagine large codebase with many errors coming from internal libraries... no idea where it happens.

Thanks
