This is an useful feature, but we can save a new option by implementing 
it as an extension to the current -e option:
  -e <n>     // stop after n errors
  -e +<n>    // stop after n new errors

Ddrescue counts as one single error area any number of contiguous 
errors, so it can increase the error counter when splitting if some good 
sectors are found inside an error area.

Thanks, but ddrescue is supposed to be a general-purpose rescue tool 
free from specific OS or device dependencies.


Best regards,
