Thanks for the suggestion.

After searching among the options used by GNU programs, I think I could 
use '-g, --progress' if finally a new option is needed.

But the true problem is avoiding mangling the output sent to stderr.

See for example what happens currently with progress output during 
compression:

  lzip -0cvv busybox-1.27.0.tar 2>&1 >/dev/null | less

For decompression it would be worse because:
1) The progress ouput would be inserted between the dictionary size and 
the rest of the --verbose output.
2) In multimember files, lzip shows --verbose output for each member 
separately.

Maybe the progress output could be shown only when stderr is a terminal?


Best regards,
Antonio.
