Once this is merged:
- merge the latest changes to commands.json in antirez/redis-doc
- re-run: utils/generate-command-help.rb > src/help.h
Then we'll have nice and easy tab-completed help in redis-cli again.
Closes#1909
updated via commands.json in redis-doc repo. Currently
use `make src/help.h` to re-generate. The following
are valid from the REPL:
help
help [command]
help [group]
help groups
ex:
help sort
help hash
