It seems to me that -e «$_» would handle most of these cases, as long as whitespace always comes in quoted so that you always end up with one word.
I would say this is hardly the case for the kind of file lists I was referring to. Not that this is terribly relevant from a world wide perspective, I guess...
That seems more general than a special option to -X ops.
Speaking of which, I like to think of (some) adverbs in terms of cmd line switches, and maybe it's just me, but I think it would be extremely useful to have a full set of tricky ones providing reasonable defaults (user-overridable, of course), short enough to be easy to type; e.g:
unlink :warn; # roughly equivalent to Perl5's # unlink or warn "Could not remove `$_':$!\n";
