[PATCH 3/3] git checkout --nodwim

[Junio C Hamano <gitster@pobox.com>]

Porcelains may want to make sure their calls to "git checkout" will
reliably fail regardless of the presense of random remote tracking
branches by the new DWIMmery introduced.

Luckily all existing in-tree callers have extra checks to make sure they
feed local branch name when they want to switch, or they explicitly ask
to detach HEAD at the given commit, so there is no need to add this option
for them.
