par2 should be able to rescan for new par files

Binary package hint: par2

This is more like a feature request.

Currently when running a par2 on a set of files, when there are more blocks in error than there are
available the app stops stating how many blocks are needed.

This is annoying especially if more par files could be made available. Annoying because the
par2 command restarts its verification of erroneous blocks (which it already did once before).

It would be easier (like programs under windows) that the app prompts to ask if the user wants
to make available more pars. If answered 'y' then the new pars are scanned for the new recovery blockcount
and if that count is large enough to recover, the recover should proceed.
