+Subject: [PATCH] Allow Invoking `zstd --list` When `stdin` is not a `tty`
+
+Also now returns an error when no inputs are given.
+
+New proposed behavior:
+
+```
+felix@odin:~/prog/zstd (list-stdin-check)$ ./zstd -l; echo $?
+No files given
+1
+felix@odin:~/prog/zstd (list-stdin-check)$ ./zstd -l Makefile.zst; echo $?
