pub fn stack_line(branch: &str) -> Result<Vec<String>>Expand description
Every branch in the stack containing branch, parent-first: the line from
the stack bottom up through branch, plus everything above it. Sibling
stacks that share only the trunk are left out - they branch off the trunk
separately, not through branch. The trunk itself is excluded; an
unanchored root stays in (path_from_root keeps it).
