I think I'd prefer a slightly more verbose name for this variable.
Also, I'd suggest you use (list #'foo ... #'bar) so that we
automatically check that those functions are known.

This should specify that it's an absolute file name.

Same here: we should explicitly say if relative file names can appear or
not in the output.

I'd appreciate if this could be better integrated with VC (so it
automatically picks up other names for other supported backends).

Why use a cons cell with the car's symbol standing for a type tag, when
the carried object is already properly self-describing (IIUC it's an
EIEIO object)?
