5f3ab823fd FIXED: format_//2: Keep different variables distinct. 
Example:

        ?- phrase(format_("~w~w", [_,_]), Ls).
        %@    Ls = "AB"
        %@ ;  false.

79cb4cd6a5 ADDED: First version of call_nth/2. 
A thread-safe implementation is possible for example with
'$nb_setarg'/3 (see #390).

e185b626bd FIXED: CLP(B): Delay BDD restriction until after the instantiation. 
This is necessary to actually take the new value into account.

Example:

    ?- sat(A*B>=C*D), A=1,B=0,C=1,D=1.
    false.

This addresses #670.

099d9aaca6 library(sgml): Correctly parse XML leaf nodes that are not text nodes. 
Example:

    ?- load_xml("<schemaRef type=\"simple\"/>", Node, []).
       Node = [element(schemaRef,[type="simple"],[])].

This is necessary for example to parse XBRL files. See #665.

dcc4b91b35 ENHANCED: flush output for impure I/O (format/[2,3], portray_clause/1 etc.) 
Without this, we do not get a (timely) prompt in cases like:

    ?- format("press a key: ", []), get_single_char(C).

whereas for example write/1 already works in such cases:

    ?- write('press a key: '), get_single_char(C).
    press a key:
