Function rustfmt_nightly::utils::indent_next_line

pub(crate) fn indent_next_line(
    kind: FullCodeCharKind,
    line: &str,
    config: &Config,
) -> bool

Based on the given line, determine if the next line can be indented or not. This allows to preserve the indentation of multi-line literals when re-inserted a code block that has been formatted separately from the rest of the code, such as code in macro defs or code blocks doc comments.
