Perhaps
- The switch between "do I use builtin, or scripted?" mechanism in
1/2 can look at an environment (just like the old "am" rewrite
series did), instead of configuration. This would make the code
a lot more simppler (you do not have to worry about the
interaction between "setup" and .git/config).
- That environment variable can be named GIT_TEST_BUILTIN_DIFFTOOL;
after all, people are opting into helping to test the new shiny
to make/prove it ready sooner.
- The bulk of the existing test for difftool can be moved to a
dot-included file (in a way similar to t/annotate-tests are
usable to test both annotate and blame-imitating-annotate).
Existing PERL prerequisites can all be lost.
- Two tests can include that dot-included file; one would
explicitly unset that environment (and gives up without PERL
prerequisite), while the other explicitly sets it.
