From: Christian Walther <cwalther@xxxxxx>
Knowing about the core.bigFileThreshold configuration variable is
helpful when examining pack file size differences between repositories.
Add a reference to it to the manpages a user is likely to read in this
situation.
Capitalize CONFIGURATION for consistency with other pages having such a
section.

doc: mention bigFileThreshold for packing
I recently spent a lot of time trying to figure out why git repack would
create huge packs on some clones of my repository and small ones on
others, until I found out about the existence of the
core.bigFileThreshold configuration variable, which happened to be set
on some and not on others. It would have saved me a lot of time if that
variable had been mentioned in the relevant manpages that I was reading,
git-repack and git-pack-objects. So this patch adds that.
Changes in v2:
* Move additions to the CONFIGURATION section at the bottom.
* Reword a little after realizing that there are more configuration
variables affecting packing.
* Capitalize CONFIGURATION for consistency with other pages having such
a section.
