We may still have code that works ONLY on the_repository, but
letting a function take "r" and lettin it ignore is worse than
leaving it explicitly limited to the_repository only, no?

By itself, Not at all.  It is the code like I am criticizing that
makes it unsafe.

I do not mind adding

	if (!r)
		BUG(...);

at the place you have the "sweep it under the rug" band-aid, though.
