Transformation from `if`...`else` to ternary causes change in behaviour

[davidtaylorhq]

Input:

result = if false && val = 1
  "A"
else
  "B"
end
puts result

(prints "B" when run)

stree format output:

result = (false && val = 1 ? "A" : "B")
puts result

This prints false when run.

It seems that the precedence of the = operator is not being considered correctly. It's also curious that the entire ternary expression has been wrapped in parenthesis - they don't seem to have any effect.

The 'correct' output would be for the parenthesis to wrap only the condition part of the ternary:

result = (false && val = 1) ? "A" : "B"

Good find! Pushing a fix now
