Junio C Hamano 30b015bffe Merge branch 'nd/repack-keep-pack'

"git gc" in a large repository takes a lot of time as it considers
to repack all objects into one pack by default.  The command has
been taught to pretend as if the largest existing packfile is
marked with ".keep" so that it is left untouched while objects in
other packs and loose ones are repacked.

* nd/repack-keep-pack:
  pack-objects: show some progress when counting kept objects
  gc --auto: exclude base pack if not enough mem to "repack -ad"
  gc: handle a corner case in gc.bigPackThreshold
  gc: add gc.bigPackThreshold config
  gc: add --keep-largest-pack option
  repack: add --keep-pack option
  t7700: have closing quote of a test at the beginning of line
