[Git cache] "Until next commit" param is broken for Redis adapter

[niosHD]

I just tried the redis cache adapter like suggested in #401 and noticed that until next commit is broken there too. Insertion into redis fails with the following error.

[ERROR] Redis Adapter : could not insert in cache, this is the error : 'ERR invalid expire time in SETEX'

I suspect that it is again related to the -1 encoding of gitolite_cache_max_time. Redis seems not too happy when -1 is specified as timeout.

Using any other timeout seems to work fine and is really blazing fast. Great job!
