pub fn expand_for_each(plan: &mut Plan, cwd: &Path) -> Result<()>Expand description
Expand a plan’s for_each block: match files via glob, apply exclude/filter,
substitute template variables into each operation, and flatten the result into
plan.operations. After this call, plan.for_each is None.
Template variables: {path}, {item} (alias of {path}), {dir},
{stem}, {ext}, {name}.
Doubled braces ({{ / }}) are treated as escape sequences and produce
literal { / } in the output. For example, {{path}} becomes the
literal string {path} rather than being substituted with the file path.
