[PATCH v1 0/2] Fix regression in checkout -b

From: Ben Peart <benpeart@microsoft.com>

Anthony Sottile <asottile@umich.edu> determined that commit fa655d8411 "checkout: optimize "git checkout -b <new_branch>" introduced an unintentional change in behavior for 'checkout -b' after doing a 'clone --no-checkout'. Create a test to demonstrate the regression then fix the bug and update the test to demonstrate the fix.
