Time output should be produced right aligned and backspaced

[mithro]

IE The output should look like

BLAH1                                                           (176 seconds)

BLAH1
BLAH2                                                           (176 seconds)

BLAH1
BLAH2
BLAH3                                                           (176 seconds)

This can be calculated by doing the following

int i = atoi(getenv('COLS'))
if (i == 0)
  i = 80;

printf("Blahh\n");
printf("\r%s(%4d seconds)", " "*30, 167);
printf("\r%s(%4d seconds)", " "*30, 165);

$ echo -e '12345\b6' 12346

This patch doesn't work when multiple tests run in parallel.
