[PATCH 0/7] [un]stage: officially start moving to "staging area"

[Felipe Contreras <felipe.contreras@gmail.com>]

In the last 13 years of discussions virtually *everyone* has agreed that
the term "the index" is not a good approximation to how most users
perceive and utilize this feature. For a summary of the discssions see
my blog post [1].

This is particularly true of newcomers, which is why everyone that
teaches git uses the term "staging area".

Among all the proposals for a better name "staging area" is by far the
one with the most consensus.

Everyone except two people agreed that "the index" is not a good term.

All non-official documentation already uses the term "staging area" [2]
[3] [4], including what is considered by most people the best
documentation out there: the Pro Git book.

There is absolutely no reason not to start using the term "staging area"
officially.

Let's start by making the staging area a first-class citizen and making
'git stage' a prominent command, similar to 'git branch'. Additionally
add 'git unstage' too.

Only *one* person expressed discontent with the term "staging area".

In favor:

* Felipe Contreras
* Scott Chacon
* Jonathan Nieder
* Matthieu Moy
* Jeff King
* Miles Bader
* Ævar Arnfjörð Bjarmason
* Jay Soffian
* Pete Harlan
* Aghiles
