[PATCH v2 1/7] Documentation: deltaBaseCacheLimit is per-thread

Message-ID
<0a6777a2431e96f1e53110fa2ce2219420b0640c.1571343096.git.jonathantanmy@google.com>
In-Reply-To
<cover.1571343096.git.jonathantanmy@google.com>

Clarify that core.deltaBaseCacheLimit is per-thread, as can be seen from the fact that cache usage (base_cache_used in struct thread_local in builtin/index-pack.c) is tracked individually for each thread and compared against delta_base_cache_limit.
