1. what: -s flag prints out of order …

   * -s flag means to stop searching the current file argument, and move to the next file argument, after the first match
   * Input loop reads lines, and a line might contain NUL
   * NUL is expected to terminate patterns in the same way as newline, but NUL was only handled correctly if -s flag was not set
   * I found this when comparing the output with and without -s
