+# Usage: $SHELL ifs.sh

+# This script generates 6856 tests for the set(1) and read(1)
+# builtins w.r.t. IFS whitespace and non-whitespace characters.
+# Each failed test produces one line on the standard output that
+# contains the test along with the expected and actual results.
+# The last output line contains the test result counts. ordered>0
+# are the number of tests where IFS=": " produced different results
+# than IFS=" :". If a test fails the same way for IFS=": " and
+# IFS=" :" then the second output line is suppressed.
