(btw -- I did try this with "emacs -Q" and it did reproduce for me)

5. Try to fold the subdir with "$". Instead of folding the subdir,
everything folds.
6. Try to kill the subdir with "C-u k" with point on the line with the
path, message: "Can only kill file lines" (expected inserted subdir to be
removed from buffer)
7. refresh buffer with "g" -- normal operations resume.
