//! Regression coverage for the indentation of composite literals nested inside other composite
//! literals in the Go documentation snippet.
//!
//! A nested literal is rendered relative to its own first column and the enclosing literal has to
//! shift its continuation lines one tab deeper; embedding it verbatim left every nested field at
//! the depth of the field that holds it, which `gofmt` rewrites. The docs pipeline never runs
//! `gofmt` over a published snippet, so the generator has to get this right itself. ~keep
