Previously, trying to round-trip label-list and name-lists with the
ToRdoc converter was not possible:
```ruby
doc = <<~RDOC
foo ::
bar ::
hi
RDOC
markup = RDoc::Markup.parse(doc)
markup # => [doc: [list: NOTE [item: ["foo ", "bar"]; [para: "hi"]]]]
rt = RDoc::Markup::ToRdoc.new.convert(markup)
rt # => "foo\nbar:\n hi\n\n"
rt_markup = RDoc::Markup.parse(rt)
rt_markup # => [doc: [para: "foo ", "bar:"], [verb: "hi\n"]]
```
This commit addresses the issue by fixing ToRdoc to generate output that
can be properly reparsed by RDoc. ToRdoc tests additionally needed to be
updated for the new output.
The old implementation of `accept_list_item_start` was copied to ToBs
because those tests did not pass with the new changes and I am
unfamiliar with the `backspace` format.
After:
```ruby
doc = <<~RDOC
foo ::
bar ::
hi
RDOC
markup = RDoc::Markup.parse(doc)
markup # => [doc: [list: NOTE [item: ["foo ", "bar"]; [para: "hi"]]]]
rt = RDoc::Markup::ToRdoc.new.convert(markup)
rt # => "foo::\nbar::\n hi\n\n"
rt_markup = RDoc::Markup.parse(rt)
rt_markup # => [doc: [list: NOTE [item: ["foo", "bar"]; [para: "hi"], blankline]]]
```

`@res` is an Array, so `@res =~ /\n\z/` calls `Object#=~` which always
returns nil.
I guess it should be `@res.last =~ /\n\z/`, but the change causes test
failures.
This bug was found during work for removal of `Object#=~`.

When you change this to true, you may need to add more tests.
