Or maybe I simply misremember what was the problem and it only truncated
the output, I'm not 100% sure, though I think it was worst than that.

Well, "universal" is maybe a bit too presumptuous, but yeah, I wanted it
to support any intenter.   However, I made it "backend-based" style, so
it can use e.g. a library, but it then requires the backend to be
written, not simply a indenter program to exist.

Isn't that a Qt program?  But yes, I wanted to do something like this --
actually each backend would export a set of options and a generic GUI
would display them and allow to edit them.
