scryer-prolog/tests/scryer/cli/src_tests/directive_errors.md
David Farrell f509d3d66f Line numbers start at 1 
Bumps the line number for the singleton warning. When the singleton
occurs on the same line at the term starts, the line number is correct:

    foo(X).

However it stills mis-reports this line number as 1 instead of 5:

    foo(1) :-
        true,
        true,
        true,
        Y.

See issue #1356.

FIXME I belive the following test should result in a error(instantiation_error,load/1) error instead of the current error.
