Since modules were introduced in the last version I found there is a need to add some form of on-hand CLI documentation for module using setups of Redis in a similar manner to vanilla-Redis commands (and the need grows as more modules are added). Also introduced lately were the syntax hints for all Redis commands, an interface which is not exposed to the module writers.

It would be of great help if this feature could be added to Redis.
I am also willing to write the code for said feature once an acceptable design has been reached by @antirez & co.

Cheers
