Warning: this command was renamed to
GETRANGE, it is called
Returns the substring of the string value stored at
key, determined by the
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.
