cut: do not accept the invalid range 0-

The command "echo 12345 | cut -b 0-" prints an empty line while
it should fail with "fields and positions are numbered from 1".

* src/cut.c (set_fields): Add a diagnostic for the invalid open
range which starts with Zero, i.e., the range 0-.
* tests/misc/cut.pl: Add tests to ensure the range 0- fails for
fields (-f) and for positions (-b, -c).
* NEWS: Mention the fix.
