+ 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.
