[PATCH v4 2/2] status:introduce status.branch to enable --branch by default

[Jorge-Juan.Garcia-Garcia@ensimag.imag.fr]

From: Jorge Juan Garcia Garcia <Jorge-Juan.Garcia-Garcia@ensimag.imag.fr>

Some people often run 'git status -b'.
The config variable status.branch allows to set it by default.

Changes since v3:
- Changes in the order in test between expected and actual.
- The number of test is the same (all posibilities that I wanted tested).
