OK this is now available at
https://github.com/candlerb/freeradius-server/commits/candlerb/redis_escaping

commit d498c4c: pushes down the xlat functionality into rlm_redis_query,
where it splits into arguments, xlats each one separately, and passes
to redisCommandArgv.

(As a side effect of this, redis_escape_func is no longer used or needed,
but I have left the code in there)

commit cfc6e78: fixes the trim functionality

I have given it a basic functional test, and it all seems OK.

Brian.
