* Version 1.22f.
+ * tests/cut/Test.pm: Add tests for new --output-delimiter option,
+ as well as for NUL input delimiter (--delimiter='').
+ * src/cut.c (cut_fields): Honor new --output-delimiter option.
+ (main): Fix handling of --delimiter='' (-d ''). Until now, it has
+ never worked as advertised. I guess no one tried it.
+
* tests/sort/Test.pm: Add two tests relating to this.
* src/sort.c (main): Stat all non-`-' input file files (and fail if a
stat fails) when an output file is specified by `-o' but doesn't exist.
