Think about what happens when you run a command like that. Bash sees
that it has an argument, which it assumes to be a script. It sets the
positional parameters and $0 accordingly. Posix and historical behavior
say that $0 gets set from the name of the script.
Then the shell attempts to open the file and read it. It discovers
the file is not a text file, and refuses to execute it, prefixing the
error message with $0 as it usually does.
