credis_set bug

[GoogleCodeExporter]

What steps will reproduce the problem?
1.call credis_set
2.provide fh, key and value args to the function

What is the expected output? What do you see instead?
KEY should be set to VALUE
Instead it gets set to sizeof(VALUE) of the provided VALUE e.g. 5 in case of 
KEY "hello".

What version of the product are you using? On what operating system?
credis 0.2.3 with redis 2.4.17 on RHEL 6.3 x86_64

Please provide any additional information below.
The attached test-client.c is compiled with the following line:
gcc -g -O2 -Wall -DPRINTDEBUG credis.c test-client.c -o test-client

Uppon executing the client, debug shows:

credis_connect() @ 768: Connected to Redis version: 2.4.17

cr_sendandreceive() @ 602: Sending message: len=21, data=SET abra 7
kadabra

cr_readln() @ 423: received 37 bytes: +OK
-ERR unknown command 'kadabra'

I'm guessing it's a parse string issue, since debug shows:
data=SET abra <val lenght> kadabra
Bbut i'm no C expert.

Checking the result with the redis_cli tool:

./redis-cli GET abra
"7"
