Also mention fgets not writing beyond \0 caveat
Also mess around with setvbuf(stdin+stdout,..) to see how it affects things (info libc, s buffering)

/* getline uses getc internally.
   includes \n & \0 on returned lines (doesn't auto add \n if not present @ EOF)
   lineptr & n can be NULL or malloced buffer.
   num chars in line (including \n) is returned so that embedded NULs can be handled.
