fix hexylena#36

particularly it has no name attribute that would be required

otherwise there is a name clash with the name attribute of the nodes

before this change the CLI for repeats was

```
if str($i_repeat....) == "when_content"
```

now its

```
if str($i_ACTUAL_REPEAT_NAME....) == "when_content"
```

if the `mako_path` parameter is passed to the `command_line` function
then the path is overwritten, i.e. if the repeat is contained in or
contains other conditionals, repeats, etc they do not appear in the
path of the produced variable.

outer element need to be first

missing deploy so far

and code simplification

but take as given

command needs to be a list

i.e. non-empty
