Binary mode import breaks with /*!999999\- enable the sandbox mode */

Hi,

When issues --binary-mode to the mariadb client it is unable to import a dump file created with the latest 10.6 version:

[root@host dba-toolkit]# cat /tmp/blaaa | mysql --host=localhost --user=root --password='' --binary-mode --init-command='SET SESSION SQL_LOG_BIN = 0; SET GLOBAL log_bin_trust_function_creators=1;' mysql

ERROR at line 1: Unknown command '\-'.

When not specifying --binary-mode, the same command works.

I suggest to prioritize this as a blocker because it breaks all kind of automation.
