test the exit status to see if a range of objects is fully
connected (or not). It is faster than redirecting stdout
to `/dev/null` as the output does not have to be formatted.

+ Suppress normal output; instead, print the sum of the bytes used
+ for on-disk storage by the selected commits or objects. This is
+ equivalent to piping the output into `git cat-file
+ --batch-check='%(objectsize:disk)'`, except that it runs much
+ faster (especially with `--use-bitmap-index`). See the `CAVEATS`
+ section in linkgit:git-cat-file[1] for the limitations of what
+ "on-disk storage" means.
