Вывод больших фрагментов текста не теряется.

Большие фрагменты текста теперь не вырезаются бесследно.
Там, откуда они вырезаются, вставляются ссылки,
по которым можно посмотреть полную версию вывода.
Испытано на больших фрагментах текста,
содержащих до 5000 строк (фрагменты более 5000 строк по умолчанию
обрезаются административно; допустимые размеры задаются в l3config.pm).
Исправлены ошибки, из-за которых большие фрагменты
обрабатывались некорректно.
