[Ada] Fix bogus style check failure with pragma Style_Checks (Off)

This fixes a bogus style check failure for long lines in rare cases
where the compiler is invoked, with a -gnatyX switch where X is neither
'm' nor 'M', on a unit which contains "with" clauses for other units
that contain a pragma Style_Checks (Off).
