A new patch is posted to the wiki, implementing the above. All modes 
will output like this when finished:

guesses: 0  time: 0:00:00:06 DONE (Mon Jun  6 19:03:01 2011) c/s:23055M

Also, I found a bug in single.c that has been there all the time since 
we got ETA. The hundredths was just a copy of the integer, so it was 
0.00%, 1.01%, 42.42% and so on.

As an even worse hack than the current code (or maybe not) I played with 
changing all get_progress functions to use a double* instead of a char* 
and return a progress with lots of decimals (though still only shown 
with two). I also circumvented the 32-bit overflow check if 
sizeof(time_t) > 4. I got really good estimates after a *very* short 
time (given a stable c/s rate). Also, I got disencouraging ETA's when 
running slow formats, like "Apr  1 12:34:56 1231432" (i.e. 1.2 million 
years from now) when running -inc:all   :-)

That last stunt has little value but I could post it if anyone wants to 
try it or polish it.
