* Assume that the input is a signature and verify it without
* generating any output. With no arguments, the signature packet
* is read from stdin (it may be a detached signature when not
* used in batch mode). If only a sigfile is given, it may be a complete
* signature or a detached signature in which case the signed stuff
* is expected from stdin. With more than 1 argument, the first should
* be a detached signature and the remaining files are the signed stuff.
