[PATCH v4 1/2] status: introduce status.short to enable --short by default

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

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

Some people always run 'git status -s'.
The configuration variable status.short allows to set it by default.

Changes since v3:
- Changes the order of the test between expected and actual.
- Format by default when status.short is not defined adequately.
- The number of test is the same (all posibilities that I wanted tested).
