All characters '\\' must be escaped in both, iso_rr_path and disk_path.
The character '=' must be escaped in the iso_rr_path and

This mode temporarily disables \-disk_pattern expansion for command \-add.
.br
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.
