It might, but it's a little out of scope in addition to your concern
about other test scripts.

     I don't know if there would be fallouts with other test scripts,

How is this for a reword of that commit description:

     t/t7507-commit-verbose.sh was using a global test_set_editor call to
     build its environment. The $EDITOR being used was not necessary for
     all tests, and was in fact circumvented using subshells in some

     To improve robustness against global state changes and avoid the
     use of subshells to temporarily switch the editor, set the editor
     explicitly wherever it will be important.

     Specifically, in tests that need to check for the presence of a diff in the
     editor, make calls to set_test_editor to set $EDITOR to check-for-diff
     rather than relying on that editor being configured globally. This also
     helps readers grok the tests as the setup is closer to the verification.

This also allows to run only specified subset of tests
with TEST_SKIP without requiring to remember which tests
are setup tests and have to be not skipped, isn't it?
