Function tokio_git_command 

pub(super) fn tokio_git_command(cwd: &Path) -> Command

A git spawn positioned at cwd.

The machine’s own git, unless a test pointed that directory elsewhere (point_git_at): a warm git can run to completion before a caller’s first poll, so a case that needs a child which cannot - a zero-budget refusal - has to drive a wrapper of its own.
