Single-line `do ... end` is not always replaced with braces

[davidtaylorhq]

Normally, syntax_tree will convert single-line do...end into braces. For example:

- expect do blah end.to(eq(5))
+ expect { blah }.to(eq(5))

However, if the parenthesis are missing from to() (as they often are in rspec code), no attempt is made to use braces. The code remains as

expect do blah end.to eq(5)

---

Context: in Discourse we previously had a number of things like

expect do
  blah
end.to eq(5)

That reads ok.

After syntax_tree formatting this has been moved onto a single line, and maintained the do ... end

expect do blah end.to eq(5)

which is not ideal.

Hmm yeah, I'll need to see why it's doing that. As you say, it should be using braces here.
