2b1692a860 ADDED: library(error): instantiation_error/1, domain_error/3, type_error/3 
These predicates simplify throwing ISO errors.

40619c8184 ENHANCED: Throw domain errors in char_type/2 for wrong types 
This is especially important because a few of our names diverge from
ctype(3), and we better inform programmers when the type they are
using is not available at all.

20fb6d6669 ADDED: library(format) now provides a rudimentary version of listing/1 
Example:

    :- dynamic(a/1).

    a(X) :- X = true, b(X).

Yielding:

    ?- listing(a/1).
    %@ a(A) :-
    %@    A=true,
    %@    b(A).
    %@    true.

listing/1 only works for predicates and DCGs that are declared dynamic/1.

608d661355 portray_clause/1 now correctly tracks variable names (#376) 
Example:

    ?- portray_clause((A :- B)).
    %@ A :-
    %@    B.
    %@    true
    %@ ;  ...

Also, change the indentation from 8 to 3 at the express request of @UWN.

60f1f1cb3d Restore the type_error, which was implemented correctly by @notoria. 
This corrects f28e87b240:
in_character is a valid type by 7.12.2 Error classification!

ab3c520006 document ~| format modifier to place a tab stop at this position 
This works best when used in tandem with ~N+, since it is currently
equivalent to ~0| and does not take the actual text position into account.
However, when using relative positions, this works as intended.

f28e87b240 instead of a type error, use a domain error 
The preceding use of atom_length/2 already ensures that C has the
correct type (i.e., atom). However, its domain may still be wrong,
if its length is greater than 1.

       Ls = [B,a,b,A]
