[PATCH] docs: checking out using @{-N} can lead to detached state

[Kaartic Sivaraam <kaartic.sivaraam@gmail.com>]

The commit message of 75d6e552a (Documentation: @{-N} can refer to
a commit, 2014-01-19) clearly specifies how @{-N} can be used to
refer not only to a branch but also to a commit. IOW, @{-N} is a
syntax for the N-th last "checkout" and not the N-th last "branch"
Therefore, in some cases using `git checkout @{-$N}` does lead to a
"detached HEAD" state.

Correct the misleading sentence which states that @{-N} doesn't
detach HEAD.
