As a general principle, we should not use "git diff" to validate the results of what git command that is being tested has done. We would not know if we are testing the command in question, or locating a bug in the cute hack of "git diff --no-index". Rather use test_cmp for that purpose.

Whether 'tis nobler in the mind to suffer

The slings and arrows of outrageous fortune,

Or to take arms against a sea of troubles,
|

And by opposing end them? To die: to sleep;
|
|
No more; and by a sleep to say we end
|
|
The heart-ache and the thousand natural shocks
|
|
That flesh is heir to, 'tis a consummation
|

Devoutly to be wish'd.
