Hi.

During mariabackup testing, I realized that for the option of "--password" I had to specify password in the commandline together.
If I use the option only without password, It says it requires a argument.

[root@maria-master full]# mariabackup --backup --target-dir /tmp/full -uroot -p

mariabackup: option '-p' requires an argument

For security purpose, It would be great that we just get the password input in next commandline like the other client tool does.

Great thanks,
