[PATCH 2/2] config: clarify compression defaults
* Clarify that core.compression provides a system-wide default to
other compression parameters.
* Explain that the default for pack.compression, -1, is "a default
compromise between speed and compression (currently equivalent
to level 6)" according to zlib.h.
