bug#35747: Add cut FIELD-LIST examples

[積丹尼 Dan Jacobson]

On (info "(coreutils) cut invocation")

with no examples for

   ‘-f FIELD-LIST’
   ‘--fields=FIELD-LIST’
        Select for printing only the fields listed in FIELD-LIST.  Fields
        are separated by a TAB character by default.  Also print any line
        that contains no delimiter character, unless the ‘--only-delimited’
        (‘-s’) option is specified.

one might even one is to put tabs in our FIELD-LIST, or maybe dashes or
commas. And maybe ranges are not supported, etc.
