[PATCH v2 0/2] checkout: learn the checkout.guess config variable

If a user does not wish to use DWIM behaviour, they must manually specify git checkout --no-guess each time. Teach checkout and switch to honour the checkout.guess config variable instead.

Changes since v1:

* Replace enumerated priority list with bullet points

Denton Liu (2):
  Documentation/config/checkout: replace sq with backticks
  checkout: learn to respect checkout.guess
