2.2.2 - Coffeescript

releaseHeader('2018-02-21', '2.2.2', '2.2.1')

Bugfix for regression in 2.2.0 where a range with a by (step) value that increments or decrements in the opposite direction as the range was returning an array containing the first value of the range, whereas it should be returning an empty array. In other words, x for x in [2..1] by 1 should equal [], not [2] (because the step value is positive 1, counting up, whereas the range goes from 2 to 1, counting down).
Bugfixes for allowing backslashes in import and export statements and lines that trigger the start of an indented block, like an if statement.
