Problem/Motivation

It's not very clearly documented but DrupalCacheInterface ::clear() accepts an array as $cid.
And MemCacheDrupal::clear() takes that already in account, but I think the current implementation could lead to unexpected behaviour.
Currently a cid array is separately handled but as far as I can tell the whole cid processing should be run on every array item of the array.

Proposed resolution

Add a loop around the whole cid handling to ensure array items with wildcards work as expected.

Remaining tasks

reviews needed

User interface changes

none

API changes

none
