Raw output mode is selected by default when STDOUT is not a tty. For
ttys, raw output can be forced using the option "--raw".

special encoding limits redefined, and all the config options for special encodings added in the example redis.conf file

Original report and fix:

SUBSTR is renamed to GETRANGE to have better consistency between command
names (with SETRANGE as its dual). GETRANGE is still aliased as SUBSTR.
