Limits
Up to a full line must be buffered from each input file during line comparison, before the next output line is written.
Some implementations read lines with the function readlinebuffer which does not impose any line length limits if system memory suffices.
Other implementations read lines with the function fgets. This function requires a fixed buffer. For these implementations, the buffer is often sized according to the POSIX macro LINE_MAX.
