Open a diff of two registers in a new tabpage. Since this is so quick to invoke it is quite useful when comparing copy-pasta code or when playing spot-the-typo. Pull up the two versions as a real diff in seconds and just close the tabpage when you're finished. If no registers are specified it diffs the most recent yank with the most recent deletion.
