I think you are trying to protect yourself from an error triggered
by unsetting what is not set, but for that, test_unconfig is
probably a better choice, as it still catches errors of other types
and ignores only that "unset a variable that is not set" error.

You can use "shift 2 &&" here (not worth a reroll).

When the caller does not give $3 to this function, it does not look
at 'expect'. I think it is clearer if you did
if test $# != 0
then
git diff "$@" >expect
fi &&
here, and ...

... wrote this as
if test $# = 0
The only difference between '-z "$1"' and '$# = 0' is when he caller
passes an empty string to the function as $3, which you never do, so
the distinction is theoretical, but using $# makes your intention
clear that you do not mean to treat an empty string any specially.
