Misleading error message if mariadb-backup --decompress option is in use

if mariadb-backup gets --prepare and --decompress options simultaneously it gives misleading error "--decompress and --apply-log are mutually exclusive"

[vagrant@build ~]$  sudo mariadb-backup  --prepare --target-dir=backup_prepare/base_backup_dir  --decompress 

[00] 2023-02-03 15:16:43 Error: --decompress and --apply-log are mutually exclusive

There is no --apply-log in the command

btw, --apply-log and --prepare docs are also a bit misleading - see MDEV-29885
