Replace this with:

m$formula <- as.formula(tform, environment(formula))

  No, I have not "lost" an environment. I manufactured a formula which lacked something needed, but without the necessary hint that I needed it. But that is semantics: A closer reread of help(model.frame) shows that the documentation is there, I had missed it.   

 I'm still puzzled by recover though.
