- fix chunked items set in binprot, read from ascii
- adds get and touch command for ascii protocol
“gat [exptime] key [key…]\r\n” will fetch the item and refresh its expiration time. This is great for keys you’d normally either manually delete, or set to 0 TTL. Items rarely hit will expire, leaving more room for others.
This command has existed in the binary protocol for a long time, but now there’s party for ascii users.
