testing with 1.3.6

## readinbg stdin
  	$ gpg --with-fingerprints < keyfile
  	gpg: Invalid option "--with-fingerprints"

  	$ gpg --with-fingerprint < keyfile
  	## this works as expected ##

## reading from keyring file
  	$ gpg --list-keys smasher --with-fingerprints
  	$ gpg --list-keys smasher --with-fingerprint
  	## these both work as expected ##

why does --with-fingerprint(s) work with list-keys but only
- --with-fingerprint works with stdin?
