dar_manager: dar process fails

Hi

I have something here, which looks like a bug in my eyes:


% dar_manager -B /mnt/sk1/Sicherung/Kataloge/D2020-07-16-03-04-34   \
              --restore home/v/abc
CALLING DAR: restoring 41 files from archive Archive/A2019-07-29-14-31-
04 using anonymous pipe to transmit configuration to the dar process
Parse error: Unknown argument given to -a : ignore-order
DAR sub-process has terminated with exit code 1 Continue anyway ?
[return = YES | Esc = NO]


There isn't any -a/--alter argument in the command line. Looks like the
dar_manager (parent) process introduces it an sends it to the dar
subprocess.
