0ddda0a864 FIXED: do not attach constraint if the propagator is already entailed and killed 
Example:

    ?- A#=A//A#==>B,A-B=1-1.
       A = 1, B = 1.

This addresses #1941.

18d0a74f23 MODIFIED: read_line_to_chars/3 is now called get_line_to_chars/3 
This is for consistency with other I/O predicates, where "read" always
indicates Prolog terms. Please adjust your programs accordingly.
