bug#14226: Sort -c takes in account fields that were outside sorting scope

[Camion SPAM]

Then, I suggest adding after -c : 
  -c, --check, --check=diagnose-first  check for sorted input; do not sort

after -k : 

  -k, --key=POS1[,POS2]     start a key at POS1 (origin 1), end it at POS2 
(default end of line) 
>> By default, if two lines are considered equivalent regarding the key

and after -s :
  -s, --stable              stabilize sort by disabling last-resort comparison

>> (See -k)

The man page is generated from 'sort --help', and there, we are trying
to favor brevity.  But it might indeed be worth adding to the 'info
sort' page.  I read that page, and notice that while '-c' and '-C' are
mentioned first, details about '-k' and '-s' are several screenfuls
away, so it is not obvious that those two options can affect the
behavior of -c.  You could help by reading that page, and finding the
spot(s) where adding a sentence would have helped you; if you could
propose the location and wording to add, then we can work with that to
turn it into a formal patch.
