[bash 4] 'test -v 1' is never true

[Alejandro Colomar]

Hi!

I wrote a script, and am trying it on many systems.  On RHEL8, which has bash 4, 
it didn't work.  I could reduce the problem to the following command, which 
never returns true:

    test -v 1;

In Debian Sid, where I develop, and where I have bash 5, that works fine, and is 
true if the function or script in which it is has any arguments.  On zsh(1) it 
also works fine.

Is this a known bug in bash?
The exact version where I can reproduce it is 4.4.20(1)-release 
(x86_64-redhat-linux-gnu).

Cheers,

Alex
