+       maint.mk: restore functionality removed by recent change...
+       Sunday's change, v0.0-8062-g6b24f60, may have appeared correct from
+       the context of a shallow-cloned gnulib repository: "git describe"
+       would fail in such a directory.  However, that change made it so
+       the reported gnulib revision no longer includes the version number
+       or a commit count, even when run from a full clone.
+       * top/maint.mk (gnulib-version): Use the full "git describe"
+       output when possible, e.g., the form above, rather than the
+       abbreviated, no-tag, no-commit-count string, and fall back to
+       using a 10-byte hash, rather than the default minimal-length
+       hash prefix, since while the minimal-length one may be fine today,
+       it is likely not to be unique for very long.
