+Subject: Probe for GNU parallel more accurately
+
+moreutils parallel isn't compatible with the command-line syntax
+used here. Because it doesn't implement GNU-style --help and exits 1
+when that option is given, this test was correctly skipped when
+using moreutils parallel, but only by mistake.
+
+moreutils parallel might conceivably gain --help and --version in
+future, but hopefully nothing incompatible with GNU parallel is going
+to gain a --gnu option.
+
+Also use the --gnu option to force the new command-line semantics;
+some versions optionally supported an incompatible command-line syntax
+taken from moreutils parallel.
