Fwd: BASH_ARGV0 do not inherit from environment variables

Mon, 07 Jan 2019 22:49:22 -0800 

Hi,

I'm not sure this a feature or bug, but:

    $ BASH_ARGV0=foo /usr/local/stow/bash/bin/bash -c 'echo "$0"'
    /usr/local/stow/bash/bin/bash

I expect $0 set to foo instead. In zsh:

    $ ARGV0=foo zsh -c 'echo $0'
    foo

Set BASH_ARGV0 after initialize the shell works as expected.
