(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.

I seem to be unable to reproduce this. But your recipe lack some
details, so I'm unsure. Would you please describe exactly what to
type after "C-c ESC" to demonstrate that some commands don't work, and
what did you expect those command to do?

Thanks.
