IMO, it is a real issue, of course.  We are breaking a reasonable use of our
editor: to change the mode and do something different with the same text.

Users should be able to change the mode and then act on the text in various ways
- e.g., treating it as just a file listing.

Yes, there is also `list-directory' that could be used for that, but that's not
a reason not to fix this, at least if the fix is straightforward.  Is the fix
onerous or something?
