The lines removed cause the shell to be identified as `fish` if the `__fish_bin_dir`, even when `$SHELL` is explicitly set to something else. This causes a fish user to get the `fish` env when running a non-fish sub-shell. All bash scripts that use `docker-machine env` will fail for fish users. Signed-off-by: Scott M.
