don't let the delta cache grow unbounded in 'git repack'
I have 4GB of RAM on my system which should, in theory, be quite enough
to repack a 600 MB repository. However the unbounded delta cache size
always pushes it into swap, at which point everything virtually comes to
a halt. So unbounded caches are never a good idea.
A default of 256MB should be a good compromize between memory usage and
speed where medium sized repositories are still likely to fit in the
cache with a reasonable memory usage, and larger repositories are going
to take quite some time to repack already anyway.
While at it, clarify the associated config variable documentation
entries a bit.
