Fix backslash escaping mechanism. Ensuring: - double backslash can't effectively recurse and form part of another escape sequence (because backslash is treated both in unistr.c and prepstdreply.c) - other non-unicode escapes aren't ignored (because they are turned into question marks in unistr.c) - first lines of included files don't 'escape' escaping because they are retrieved in begin_new_*() rather than get_processed_text_line(). - files intended to be included transparently aren't escaped, and upcoming lines aren't doubly escaped
