Subsequent updates to branches always creates new file under
`$GIT_DIR/refs` hierarchy.
+A recommended practice to deal with a repository with too many
+refs is to pack its refs with `--all --prune` once, and
+occasionally run `git-pack-refs \--prune`. Tags are by
+definition stationary and are not expected to change. Branch
+heads will be packed with the initial `pack-refs --all`, but
+only the currently active branch heads will become unpacked,
+and next `pack-refs` (without `--all`) will leave them
+unpacked.

This option causes branch tips to be packed as well. Useful for
