Subject: [PATCH] Exit with status code 2 if no files were given

By convention exit(1) is reserved for general errors, while exit(2)
means command misuse. Stdlib `flags` package invokes `os.Exit(2)`
after printing out the usage message. This commit changes the empty
files list exit code to be aligned with this behavior.
