pub fn exec_capture_in_dir(
dir: &Path,
program: &str,
args: &[String],
) -> (ExecStatus, Vec<u8>)Expand description
Like exec_in_dir, but CAPTURE stdout+stderr (stdout then stderr)
instead of inheriting the parent’s stdio. Used by run_in_dirs_parallel
so concurrent worktrees don’t interleave their output — each block is
printed whole, in worktree order, after the fan-out completes.
