30759	Make cache.delete() return whether or not it suceeded.	Simon Charette	Daniel Rios	"It can be quite useful when dealing with complex caching/locking systems or simply for logging purposes.

Memcache clients already returns this value and it should be straigtforward to implement for file, inmemory, and database backend based on the number of returned rows.

Redis `del` operation also returns the number of keys it successfully deleted so it should be implementable if it's eventually added as discussed on the mailing list."	New feature	closed	Core (Cache system)	2.2	Normal	fixed			Accepted	1	0	0	0	0	0
