Hmm. Perhaps 'git-gc' should always call 'prune' with the '--expire' argument
for simplicity of the 'git-gc' interface and --prune should become a noop?

Is 'git-gc --prune' still useful to end users when those in-the-know can use
git-prune when they really want all loose unreferenced objects to be removed?

Also, what about clones created with --shared or --reference? Should there be
a way to disable this functionality? gc.pruneExpire never
