Thanks, this patch is much cleaner in its approach, and I don't have

be more consistent with the one above in scan_directory().  The
version for v11 has required a bit of rework, but nothing huge
either.

What you have here is much more simple than the original proposal, so
I kept it.  Applied and back-patched down to 11.
