3c467c0d22 (limfield): #ifdef-out a block of code that makes 
GNU sort incompatible with Unix sort when a key-end spec refers
to the N'th character in a field that has fewer than N characters.
The POSIX spec doesn't appear to specify behavior for this case.
From Karl Heuer.

e6fae6c23f [SORT_FAILURE]: New macro. 
Be careful to exit with 1 only when -c is used and the
input is not properly sorted.  In all other cases, use
SORT_FAILURE as required by POSIX.
(main): Change some `error (1, ...' to use SORT_FAILURE.
Upon successful termination, exit with EXIT_SUCCESS instead of `0'.
Replace all uses of `2' (as exit code) with SORT_FAILURE.
