Before I push it, I'd like to confirm that you meant to say "... compatible with Bash 4.1 and *earlier*" in the subject. We've been already 4.2 compatible and the new construction probably was in bash since version 2, so I would change it. Thanks.

KVM unit tests scripts/arch-run.bash uses test -v to check whether a variable was set. The -v switch was introduced in Bash 4.2. This patch uses test -n to to achieve equivalent functionality that is backward compatible. Add double quotes around source strings for read commands. On older Bash versions, without the quotes the read will parse the string into its components but then place them all into a single variable separated by spaces rather than into separate variables as the script intends. Add check for missing commit in errata file. Tested: Ran with an injected empty commit field in errata.txt to verify with git://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git at 073ea627a4268333e0e2245382ecf5fabc28f594.
