Add global error message while preserve default behavior

[thewh1teagle]

Hi,
I have the following program:

use eyre::{bail, Result};

fn test() -> Result<()> {
    bail!("Error!")
}

fn main() -> Result<()> {
    test()?;
    Ok(())
}

Which prints the following error by default:

Error: Error!

Location:
    src/main.rs:4:5

I would like to add global context to every error that may happen so it will looks exactly like:

Error: Error!

Location:
    src/main.rs:4:5

In case this is unexpected, report it here:

I tried to use eyre/examples/custom_handler.rs but it doesn't include the location of the error.
