eslint-plugin-consistent-return-legacy

The consistent-return rule from ESLint 1.x.

In ESLint 1.x (as in this plugin), the rule only verifies that all or none of the return statements return a value.

For example, this would be legal:

function() {
  if (foo) return foo;

  if (bar) return bar;
}

In ESLint 2+, it verifies that all or none of the code paths return a value.

So the first example would not be legal; you'd need to do this:

function() {
  if (foo) return foo;

  if (bar) return bar;
  
  return baz;
}

In some code the new behavior may produce many false negatives, e.g. when returning false in jQuery event handlers.
