Obviously, there's a problem in the inconsistent parsing of
dired-listing-switches, where the basic code splits it at spaces without
doing any additional unquoting or analysis, whereas the Tramp code seems
to just pass it as-is to the shell (so if you set it to "-al $(rm -rf ~/.)"
it will try to do something funny).
I won't claim that the basic code's naive splitting is great, but
Tramp's similarly naive use is not great either. So, I suggest to treat
it as a bug in Tramp which should split it like the basic code and then
shell-quote-argument the parts.
