Soft redirect vs single line
I've restored the soft redirect to Wiktionary, which was first done in 2012 but contested at the time. This is because:
- The article is about eight years old and has never expanded beyond a dictionary definition.
- The current wording is too narrow - "all-clear" is a common phrase and is routinely used in non-military contexts. But appropriately broadening the context unfortunately merely leaves us with the Wiktionary entry.
