Empty hashes are put on the previous line in _dump_string()

[Corion]

The following program creates invalid output:

#!perl
use 5.020;

use YAML::Tiny 'Dump';

say Dump {};

__END__

--- {}

This happens because in _dump_string , the line gets appended indiscriminately to the document delimiter:

...
            } elsif ( ref $cursor eq 'HASH' ) {
                unless ( %$cursor ) {
                    $lines[-1] .= ' {}';
                    next;
                }
                push @lines, $self->_dump_hash( $cursor, $indent, {} );

I don't know what a good fix would be here. Maybe explicitly checking that we are not appending to the line --- .
