bug#12903: "cut -b 0-" is supposed to be invalid

[Marcel Böhme]

   Hi,
   The command "echo 12345 | cut -b 0-" prints an empty line while it
   should fail with "fields and positions are numbered from 1" according
   to this specification "cut: diagnose a range starting with 0 (-f 0-2)
   as invalid".
   Can you confirm this is an incomplete bugfix made on 2007-05-22?
