[PATCH v3 4/5] commit test: test_set_editor in each test

[Caleb Thompson <cjaysson@gmail.com>]

t/t7507-commit-verbose.sh was using a global test_set_editor call to
build its environment.

Rather than building global state with test_set_editor at the beginning
of the file, move test_set_editor calls into each test.

Besides being inline with current practices, it also allows the tests
which required GIT_EDITOR=cat to avoid using a subshell and simplify
their logic.
