Function normalise_machine_paths 

pub fn normalise_machine_paths(
    text: &str,
    root: &Path,
    home: Option<&Path>,
) -> String

The repository root written as <repo> and the home directory as <home>.

These are mj_uc_normalise’s first rules, in its order: the canonical (symlinks resolved) spelling of the root, then the spelling the caller gave, then the home directory. The canonical spelling goes first because the given one can be a suffix of it (a temporary directory reached through a symlink), and the root before the home because a checkout usually lives inside one. A trailing separator is not part of a spelling, and a spelling that is empty without it, the filesystem root, replaces nothing.
