Subject: [PATCH v3 14/14] doc: promote "git switch-branch" and "git restore-files"

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Thu, 29 Nov 2018 22:58:49 +0100

The two new commands "git switch-branch" and "git restore-files" are
added to avoid the confusion of one-command-do-all "git checkout" for
new users. They are also helpful to avoid ambiguation context.

For these reasons, promote them everywhere possible. This includes
documentation, suggestions/advice from other commands...

"git checkout" is also removed from "git help" (i.e. it's no longer
considered a commonly used command)
