Line up altdisplay expected strings on one line
...
Rustfmt does not like how these were previously formatted and insisted
on doing:
const EXPECTED_ALTDISPLAY_G: &str = "\
f failed: oh no!\
";
which is worse.

Eliminate backtrace_if_absent in Error::context
...
This avoids stepping through the list of causes when adding context to
the anyhow::Error type which is known to already hold a backtrace.
Reduces the release-mode time of the following loop from 4 seconds to 4
milliseconds.
let mut err = anyhow!("...");
for _ in 0..25000 {
err = err.context("...");
}
