As my internet connection is far from optimal -- to put it mildly --
and power outages also frequently occur with a duration that even a UPS
equipped with a 12V, 65Ah car battery can't cope with, some kind of
'continue where left off' for the -x option for single large file
recoveries would be *extremely* attractive in this kind of situation.

thanks

P.S. My humble apologies if (again) I didn't read the manual carefully
enough... :)
