Changing to doc problem for now (IIRC, there is at least one
duplicate of this ticket).

This is intentional. PR #4474 is also still relevant, because it is a change specific to includes (not normal file reads).

UPGRADING currently only mentions this change for fread() and fwrite() in particular, but of course it also affects many, many other filesystem functions that read/write internally. I don't think we want to exhaustively list everything that might be affected.

Well, the behavioral change has been introduced with commit
1cbcf0f[1]; not sure whether this particular behavior has been
anticipated.  If so, PR #4474[2] appears to be superfluous now.

This is not particularly related to hash_file(), but also affects
other filesystem functions, see <https://3v4l.org/5XQB3>.  IIRC,
that was a very deliberate change/fix.
