This change makes our baseline system use CRLF for line endings end to
end. This isn't needed for correctness, but it helps with quality of
life when developing on OSX.
This will avoid churn to the baseline files related to line endings when
updating.
This might only take effect if you nuke the TestFiles directory and
check it out again.
Most versions of NPM in use always use LF for line endings anyway.
Forcing LF on windows should limit the number of no-op changes.
This issue has been fixed in NPM
(see https://github.com/npm/npm/issues/1716) but not everyone will have
the fix.
