5d3295c40c ENHANCED: use newly available read_term_from_chars/3 for better errors 
Examples, previously:

    $ scryer-prolog -g "member(X,Ls"
    ?-
    $ scryer-prolog -g "member(X,Ls)"
    member(_542,_543) causes: error(existence_error(procedure,member/2),member/2)
    ?-

Now:

    $ scryer-prolog -g "member(X,Ls"
    "member(X,Ls" cannot be read: error(syntax_error(incomplete_reduction),read_term_from_chars/3:0)
    $ scryer-prolog -g "member(X,Ls)"
    member(X,Ls) causes: error(existence_error(procedure,member/2),member/2)
    ?-

This also addresses #1185.
