kvget always include new-line character

[damphat]

small problem

"bob" has 3 chars, but kvget return string of 4 chars

[kv-bash]# source ./kv-bash
[kv-bash]# kvset name "bob"
[kv-bash]# kvget name > output
[kv-bash]# stat -c%s output
4
[root@localhost kv-bash]# rm -f output

The reason is kvget echo with a new-line character
