[PATCH v2 0/2] tr2: shows the scope unconditionally with config

[Teng Long <dyroneteng@gmail.com>]

From: Teng Long <dyroneteng@gmail.com>

Diff from v1:

* Fix the premature code in [1/2] by Junio's comment in:

  https://public-inbox.org/git/xmqqy1wkc0yw.fsf@gitster.g/

* Optimize the documentaion in [1/2] by Ævar's comment in:

  https://public-inbox.org/git/220722.86fsits91m.gmgdl@evledraar.gmail.com/

I send this patch version a little earlier maybe because some context not fully
discussed or solved, intend to avoid context signal disappearance because it's
been lasted a while now. 

Thanks.
