Oh, and it already hit master while I wasn't paying attention!  Patch 1
is fine, but 11be65cfa4 (diff: fix --exit-code with external diff,
2024-05-05) is flawed: It assumes external diffs write to their stdout,
which is not documented and not necessarily true or practical for GUI
tools.  Could you please revert it for now?

My current understanding is that we can optionally let external diffs
report that two files have no meaningful differences using exit code 1,
requiring no further config settings or output piping. disagrees, however, and I have yet to look into these
test failures -- and write a bunch more tests.

Sorry for the kerfuffle.
