crasher with certain sources

[paulp]

Edit: somehow I thought it was the trailing newline, but it isn't. However it's definitely that source.

scala> parse("m50d/paperdoll/scalaz/src/main/scala/paperdoll/scalaz/StateLayer.scala") collect { case x: Name => x }
parsing(/s/github/m50d/paperdoll/scalaz/src/main/scala/paperdoll/scalaz/StateLayer.scala)
java.lang.IllegalArgumentException: [2353..2352) is not a valid range

If I wrap the Name toString in a Try we see...

Success(A)
Success(S)
Success(A)
Success(StateHandler)
Success(initialState)
Failure(java.lang.IllegalArgumentException: [2353..2352) is not a valid range)
Success(translateState)
Success(F)
Success(_)
Success(S)
Success(ms)
Success(MonadState)
Success(F)

So I think it's actually related to EOL conventions. That file has old school \r\n going on. Comparing string literals which parse to file slurped data which throws that exception, line endings are the only difference I detect.

Just checked now, and the file parses successfully with scala.meta 1.6.0.
