+Returns the substring of the string value stored at `key`, determined by the
+offsets `start` and `end` (both are inclusive).
+Negative offsets can be used in order to provide an offset starting from the end
+of the string.
+So -1 means the last character, -2 the penultimate and so forth.
+
+The function handles out of range requests by limiting the resulting range to
+the actual length of the string.
