bootstrap: When a commit is specified, do a shallow fetch if possible. Rationale and explanation: <https://lists.gnu.org/archive/html/bug-gnulib/2021-10/msg00073.html>. * bootstrap: When a commit hash is specified, ask for this specific commit on fetch, and fallback to fetching the entire repository if fetching by commit hash fails.
