Back out rev 1.19 because

Browse Source 
1) It breaks uniq for real life languages when "substitute" directive used in
the collating table.
2) It breaks uniq usage in tool chain with other localized utilities which
use collate.
3) To follow LC_COLLATE it is directly allowed for uniq
by POSIX P1003.1 Draft7 (7.3.2). It means that rev 1.19 gains no additional
POSIX conformance.
