Indeed, that's far better than using an absolute url with scheme etc.

That's not correct. File externals are supported (since 1.6 I think).
They have a couple of specific problems though (a lot of which have
been fixed in 1.7), because their implementation is entirely different
from directory externals (file externals use the "switch" mechanism
underneath, while dir externals are essentially an embedded checkout
with some sugar on top).
So, concerning to the problem of the OP:

So essentially you are "injecting" a file external (file_b1.txt)
inside a directory external (FOLDER_C (an external of FOLDER_A)).
Hm, I remember some past discussions about edge cases like these
(during the working copy rewrite of 1.7), but I don't remember exactly
if this is actually a supported use case, or if it just happened to
work by accident in 1.6.
Perhaps someone else on this list can shed some light on this?
