The documentation of the
[https://www.gnu.org/software/bash/manual/bash.html#Bash-Conditional-Expressions
Bash-Conditional-Expressions] "-v varname" says:

> -v varname
>    True if the shell variable varname is set (has been assigned a value).

I think "export TEST_EQUAL_WITHOUT_VALUE=" does not assign a value to the
varname, does it?

Test case:
> docker run -it --rm bash:latest
> export TEST_EQUAL_WITHOUT_VALUE=
> if test -v TEST_EQUAL_WITHOUT_VALUE; then echo "true"; else echo "false";
fi

The output is "true", but there is no value assigned to it.

That is fine to me. I suggest to change the documentation and remove the "(has
been assigned a value)" part.


Tested with: GNU bash, version 5.2.26(1)-release (x86_64-pc-linux-musl)
