[PATCH 3/3] Revert "bash prompt: avoid command substitution when finalizing gitstring"

[Brandon Casey <bcasey@nvidia.com>]

From: Brandon Casey <drafnel@gmail.com>

This reverts commit 69a8141a5d81925b7e08cb228535e9ea4a7a02e3.

Old Bash (3.0) which is distributed with RHEL 4.X and other ancient
platforms that are still in wide use, does not have a printf that
supports -v.  Let's revert this patch and go back to using printf
in the traditional way.
