fixes https://github.com/lightbend/genjavadoc/issues/220

i only tested this on 2.13.5 locally, let's see what travis says.

@raboof this went green. not sure what's the best strategy for testing, i added a commit that tests everything with -Yrangepos. I think either the test suite should just use the compiler's default (so rangepos will be on for 2.13.4+), or everything should be tested twice (with and without rangepos).

[lrytz]

In this case I'd suggest to remove the rangepos overrides in the tests, so that it tests the compiler's default.

@raboof could you test this on Akka (2.12.13, 2.13.3, 2.13.5)? Would you prefer to have a release or do your own publishLocal?

(failure seems spurious, and travis doesn't let me restart the job, "Oh no! An error occurred. The job could not be restarted")

I'll give it a go (with publishLocal)

Thanks!

Tested a couple of variations:

With genjavadoc 0.16 and default settings:

• 2.12.13 and 2.13.3: ok, 2.13.5 not ok (as expected) With genjavadoc 0.16, enabling -Yrangepos explicitly:
• 2.12.13 and 2.13.3: both not ok (as expected)

With this branch and default settings:

• 2.12.13, 2.13.3 and 2.13.5 all ok With this branch, enabling -Yrangepos explicitly:
• 2.12.13 and 2.13.3 both ok

So all good!

Thanks for testing it!
