Update: this is actually redundant This Node has a better explanation...

If it were only that simple :) If you'd looked above these lines, you would have seen that they were within the 'checkbox_group' and 'radio_group' subs (although I think your line number is off in the second case). You need to do a little less casual grepping :)

After a little play, I think I've narrowed it down to (and sent a note to Lincoln explaining my thoughts) this sub: 

sub _make_tag_func {
    my ($self,$tagname) = @_;
    my $func = qq(
    sub $tagname {
            shift if \$_[0] &&
                    (ref(\$_[0]) &&
                     (substr(ref(\$_[0]),0,3) eq 'CGI' ||
                    UNIVERSAL::isa(\$_[0],'CGI')));
        my(\$attr) = '';
        if (ref(\$_[0]) && ref(\$_[0]) eq 'HASH') {
        my(\@attr) = make_attributes(shift()||undef,1);
        \$attr = " \@attr" if \@attr;
        }
    );
    if ($tagname=~/start_(\w+)/i) {
    $func .= qq! return "<\L$1\E\$attr>";} !;
    } elsif ($tagname=~/end_(\w+)/i) {
    $func .= qq! return "<\L/$1\E>"; } !;
    } else {
    $func .= qq#
        return \$XHTML ? "\L<$tagname\E\$attr />" : "\L<$tagname\E\$at
+tr>" unless \@_;
        my(\$tag,\$untag) = ("\L<$tagname\E\$attr>","\L</$tagname>\E")
+;
        my \@result = map { "\$tag\$_\$untag" }
                              (ref(\$_[0]) eq 'ARRAY') ? \@{\$_[0]} : 
+"\@_";
        return "\@result";
            }#;
    }
return $func;
}

My guess is that \@_ is always true at the moment, so it never tries to create the XHTML non-container element (it's a little easier to see if you dump the output of the compiled br sub).
