# Before 2020-12-13, the directive unexport-env wrongly accepted arguments
# and ignored them.
#
# Before 2020-12-13, misspelled directive names like "unexport-environment"
# were not properly detected.
# TODO: Implementation
.unexport-en # oops: misspelled
.unexport-env # ok
.unexport-environment # oops: misspelled
.unexport-environment # misspelled
# As of 2020-12-06, the directive unexport-env is not supposed to accept
# arguments, but it does without complaining about them.
