Subject: [PATCH 02/32] Tweak dotty-specific source directory (#62)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In the dotty community build, the version is forced to something other
than 0.10 (e.g. 0.12.…), so scala-2.10 isn't taken into account without
this change.
