Mike Fährmann 8fe9056b16 implement string slicing for format strings ...

It is now possible to slice string (or list) values of format string
replacement fields with the same syntax as in regular Python code.

"{digits}"       -> "0123456789"
"{digits[2:-2]}" -> "234567"
"{digits[:5]}"   -> "01234"

The optional third parameter (step) has been left out to simplify things.
