I think this is what I will implement.  In addition verifying a detached
signature in --batch mode will required that both files are given and
fail otherwise.  After all the mode where gpg figures out the data file
is a convenience feature which is indicated by

 gpg: assuming signed data in 'FILE'

in --verbose mode.  This will break scripts using the abbreviated
command line version but it is better they break for a valid signature
than accepting faked signatures.  Note that this bug also affects gpgv.

That is an entire different thing and not a problem of gpg.  You have
the very same problem with all tools and URLs.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
