input() is used to accept filenames when saving, regular expressions when searching, and other input. It writes the characters into buffers such as file and exp_buf and others which are of length LINE_LEN. To prevent writing beyond the end of the intended buffer, truncate the input at LINE_LEN - 1 and ensure that the string is NULL terminated. Change-Id: I142baa8cfae38bdd7fa648d86559d6d9b8e7a7fd
