Thanks, I'll push it unless someone comes up with a better wording.

Admittedly, compared to the academic question behind "--no-preserve-root"
(which is like "what happens to me when the globe under my feet disappears?"),
there may be more real-world reasons to remove ".".

However, as it's possible to pass the canonicalized file name of "."
or ".." to rm(1), I'm not yet convinced that it warrants adding a
new --no-preserve-dot-or-dotdot (and for symmetry reasons a new
--preserve-dot-or-dotdot) option.

Have a nice day,
