Parser silently ignores unclosed or missing media block at end of file

[kevinoid]

Currently Parser silently ignores a malformed or missing block for a media query. Some examples are:

@media (min-width: 500px) {
  .sometimes-big {
    font-size: 5000px;
  }

@media (min-width: 500px)

@media

The missing block is also silently ignored when placed at the end of another block. For example:

.sometimes-big {
  font-size: 5000px;

  @media (min-width: 500px)
}

.red {
  font-color: red;
}

Although the first behavior (silently ignoring unclosed blocks) is the only one which concerns me, I noticed the other behavior while investigating and felt it worth mentioning.

It appears both issues could be fixed by adding an error() when .block() returns falsey at parser.js:1282, but this would trample some other error messages in the test suite and it wasn't apparent to me how to avoid that, so I hope you'll forgive the lack of a PR to address the issue.

Thanks for considering!

thanks for investigating the bug at least. It may be that the error test messages just need updating.

Looks great, thanks @lukeapage !
