All characters '\' must be escaped in both, iso_rr_path and disk_path.
The character '=' must be escaped in the iso_rr_path and
may or may not be escaped in the disk_path.
This mode temporarily disables -disk_pattern expansion for command -add.
@*
Mode "on" does nearly the same. But '=' must only be escaped in the iso_rr_path
and '\' must not be escaped at all. This has the disadvantage that one
cannot express an iso_rr_path which ends by '\'.
@*
Mode "off" disables pathspecs of the form target=source
and re-enables -disk_pattern expansion.
