I appreciate this change. Without [PATCH 2/2] applied I'm getting:

  Runtime executable paths
    perl         : /usr/bin/perl
    python       : /usr/bin/python3
    shell        : /usr/bin/sh

And with [PATHCH 2/2] I'm getting:

  Runtime executable paths
    perl         : /usr/bin/perl
    python       : /usr/bin/python3
    shell        : /bin/sh

As expected. :+1:
