# This test compares "known good" output with various settings against output
# with the current code. It's brittle by nature, but this is probably the
# "best" approach possible.
#
# Notes:
# * options passed to this script (such as -v) are ignored, as they would change
#   the output and break the test
# * the number of asterisks after a "banner" differs depending on the number of
#   columns on the TTY, so we must adjust the columns for the current session
#   for consistency
