Scala Code Comment highlighting in green to end of document if Equals not followed by a Space

I think this issue might be reported with different triggers.

I did not see this particular trigger so I've added a new request in the hopes that it help clarify the problem(s).

I suspect that when one falls the rest will follow :)

Then again I'm an optimist...

In a line of Scala with an equals sign the "green -- ergo this is a comment" colouring goes to the end of the document IF the equals does not have a space after it.

```
atom -v
Atom : 1.19.5
Electron: 1.6.9
Chrome : 56.0.2924.87
Node : 7.4.0

```
Sample one with space: GOOD


Sample two without a space: BAD


No source file, test, or entry point is named. Reproduce the Scala syntax-highlighting case described in the issue, comparing an equals sign followed by a space with one that is not. Done means the comment coloring no longer extends to the end of the document in the reported case.
