Apart from s/types.string/types.str/ (or types.lines where appropriate):

my-env: Support for running command directly by load-env-xxx script

First I don't think there is a reason to run shell as a child of

Also it's often useful to just run a command inside the environment
load-env-xxx command --args

Closes #3254
