[PATCH 1/2] cindex: improve progress display

[Eric Wong <e@80x24.org>]

Instead of displaying the total number of changes across all
repos next to the repo path ("$GIT_DIR: $TOTAL commits"), we'll
only show the number of changes made in that repo.

We'll also note when a prune is complete on a shard, since
prunes may often be expensive no-ops.
