True. That's why I was suggesting to add this information only when
relevant.

Actually, I was giving this example to fix the ideas, but my problem
is different:

I'd like to write some fancy features related to show-changeset in
xtla (Emacs interface to tla). For example, an interface with ediff.
Here's how this would work:

tla-show-changeset already displays a buffer in diff-mode. The user
may like it, or may not and type `e' to start an ediff session (like
you can already do with tla-changes). For that, I need to get the full
file of both the base and the modified version (otherwise, I can't
just invent the context), and for that, I need to know where to find
those files.

It seems there is no way to do so currently.

This wouldn't be a "killer feature", but could be usefull in some
contexts, so, if it can be added in a backward compatible way, I think
that could be nice.
