Add string condensing for the ETA output

If you run a lot of jobs, the ETA output string will become way too
long. Add some condensing so that instead of displaying:

Jobs: 80 (f=80): [rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr] [10.2% done] [2110MB/0KB/0KB /s] [540K/0/0 iops] [eta 53m:55s]

we just display

Jobs: 80 (f=80): [r(80)] [10.2% done] [2110MB/0KB/0KB /s] [540K/0/0 iops] [eta 53m:55s]

instead.
