[tex-live] Having a .fmt for different engines

[Karl Berry]

    Others probably understand all this much better than I do, though....

Thomas does, I'm sure.  I don't.

Anyway, we are not going to radically revamp fmtutil a couple weeks
before the release, that's absurd.  I can't even think about it now.  If
someone can send me a patch of a few lines that improves the situation,
I will consider that.  If it's complicated, it'll have to wait.  Sorry.
