collapse-preserve-inline does not preserve simple, single line ("return") statements

[octavian-nita]

Hi guys,

As indicated, when using "brace_style": "collapse-preserve-inline" in .jsbeautifyrc, simple, single-line statements don't seem to always be preserved. At least one such case is when the 'simple' statement is a return: for a function definition such as

function foo(arg) {
  if (!arg) { return false; }
  // ...
  return true;
}

I get (after beautifying)

function foo(arg) {
  if (!arg) {
    return false; }
  // ...
  return true;
}

whereas I would have expected no change in the input.

Needless to say, I am using the latest version of js-beautify.

yes, this is a bug, there are some places where they are not preserved. Mostly due to specific keywords.
