Add ".externalToolBuilders/" and "*.launch" 

Force.com sample file

*** .externalToolBuilders/
This directory stores project-specific launch configurations for external tool builders, such as ant tasks that have to be executed to fulfill the build lifecycle

*** *.launch
It is possible to store "eclipse launch configurations" in external files. These (XML-)files may be stored anywhere within your projects and will be discovered by Eclipse automagically.

The behavior is documented in [1].
The prefix doesn't seem to be documented, but it is hardoced as described in [2].
