31654	Memcached key validation raises InvalidCacheKey with clunky message.	Tim McCormack	Mariusz Felisiak	"On Django 2.2.13 the code for `memcache_key_warnings` in `django/core/cache/backends/base.py` has a bad format string that results in raising an exception rather than just producing a warning. This can be reproduced with a memcached key with a space in it, e.g. `""foo bar""`.

This code was present before the 2.2.13 release, but becomes more exposed with that release, since it begins validating cache keys.

I think it's as simple as removing the `, CacheKeyWarning`."	Bug	closed	Core (Cache system)	2.2	Release blocker	fixed	memcached		Accepted	1	0	0	0	0	0
