Fix: Do not naively decode output just for logging
Fix: Do not naively decode output just for logging

In case `decode` is `False`, especially to avoid our standard decode
error handling, the automatic logging would have thrown anyway.

Just avoid the decoding here altogether as `log_git` does that for us
in a defensive way t.i. without throwing.
