Re: glibc calls more write() than necessary

I first agreed to this, but I then tried the following test case:

int
main (int argc, char **argv)
{
  printf ("\n"); /* Does not work when there is only one printf.  */
  printf ("\nhello\n\n\n\n\n\n\n\nee\nee\n\n\n\nee\n\n\n\n\n\n");
}

So flushes are already sometimes done together.

Note: The second printf compacts the write only if there was already a
non-empty printf before.  I guess it depends on whether a buffer has
already been allocated or not.
