  "message": "checkout branch: prime cache-tree fully\n\nWhen switching to another branch, the earlier code relied on incremental\ninvalidation of cache-tree entries to degrade it.  While it is not wrong\nper-se, we know that the resulting index must fully match the branch we\nare switching to unless the -m (merge) option is used.\n\nWe should simply fully re-prime the cache-tree using the new tree object\nin such a case.  And for safety, invalidate the cache-tree as a whole in\nother cases.\n\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
