A subshell is not an interactive shell, so INTERACTIVE_COMMENTS does not
make any difference here, except that it delays treating "#" as a comment
until after the subshell has begun.  In bash for example the "#" would
comment out the closing paren and your expression wouldn't work at all.

Also, because NO_INTERACTIVE_COMMENTS is the default, propagating it from
the command line into subshells would break many of the same things that
you are concerned about being broken by histchars='!^'.
