[Bug-ddrescue] Progress indicators

[David Morrison]

One of the things I struggle with is knowing where ddrescue is up to. 
The display shows quite a lot of information in the initial scan 
(ipos/opos go up), and even in the first attempt to scrape the bad 
blocks from the first pass (non-scraped counts down to zero, read 
errors and bad areas go up). However, in its retries of the bad 
blocks, there is not really much indication of where it is up to. 
Read errors continue to go up, and ipos/opos change, but these are 
not helpful unless you know how many bad blocks it has yet to scan.

Is there some way to know how far through a retry it has got? (Yes, 
the mapfile would probably say, but as I described earlier, I do not 
have a mapfile due to an oversight. :-(

Thanks
