How to avoid an implicit "return" in coffeescript in conditional expressions?

I am implementing a function that has deferred value to return and within the function I have many nested conditional expressions:

e.g.:

deferred = Q.defer()
FS.readFile("foo.txt", "utf-8", (error, text) ->
    if error
      deferred.reject(new Error(error))
    else
      deferred.resolve(text)
)
return deferred.promise

which than will be compiled into:

var deferred;

deferred = Q.defer();

FS.readFile("foo.txt", "utf-8", function(error, text) {
  if (error) {
    --> return <-- deferred.reject(new Error(error));
  } else {
    --> return <-- deferred.resolve(text);
  }
});

return deferred.promise;

I need only the last return, but not the if/else returns (i.e. --> return <-- in the compiled code)

How can I avoid such a behavior (implicit returns where they are do not needed) of the coffeescript compiler?
