It wasn't among the proposed solutions.

I went with the env var solution initially (because it required less 
code and brought fewer -- none -- Git version compatibility problems), 
but it didn't yield itself as easily to the per-action opt-in as the 
other proposal (currently installed).

But now that I think about it, it would be possible to do this without a 
new macro, just adding a new variable that default to nil, and set it to 
t in every backend method that needs it.
