(Reported by @k0kubun san in ruby-jp slack #mruby channel)

yaml = 'foo:
- /bar
- /baz'
puts YAML.dump(YAML.load(yaml))

psych

---
foo:
- "/bar"
- "/baz"

mruby

---
foo:
- /bar
- /baz

Psych seems to change the style of scalar depending on what's inside:
https://github.com/ruby/psych/blob/7bebf65e4d90a75b79057e50a89ca5af3f53500a/lib/psych/visitors/yaml_tree.rb#L277-L278

So we need to change the style like psych here:

mruby-yaml/src/yaml.c

Line 373 in d925845

yaml_scalar_style_t style = YAML_ANY_SCALAR_STYLE;
