+Enhancement: Add flag to source the backup from a program's standard output
+
+The `backup` command now supports sourcing the backup content from the standard
+output of an arbitrary command, ensuring that the exit code is zero for a
+successful backup.
+
+Example: `restic backup --stdin-from-command mysqldump [...]`
