From: Christian Walther <cwalther@gmx.ch>

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.
