# Before 2020-12-06, the directive unexport-env was implemented strangely.
# According to its documentation, it does not take any arguments, but the
# Implementation accepted variable names as arguments and produced wrong debug
# logging for them, saying "Unexporting" for variables that at this point were
# not exported anymore.
