  B::Deparse: better output of anonhashes following map, grep, sort

When a `map`, `grep`, or `sort` keyword is followed by an anonymous hash
constructor, disambiguated from a block declaration by a plus character,
`B::Deparse` struggled to always include the plus in its output, meaning
that deparsed Perl code would behave differently to the original.

For example:

    map +{ $_ => 1}. 1

would deparse to:

    map { $_ => 1}, 1

It now deparses correctly - for at least some cases of the same form.
