With the new sync logic in CRW-1846 that uses the standard sync.sh and get-sources.sh scripts common to other builds, a problem has occurred in that we are committing lots of "nuissance commits" to the repo every time we regenerate the CSV and nothing but the timestamp has changed.

Solution is to check if the proposed commit includes a diff that is more than just a one-line timestamp change, and if so, undo the proposed change and don't commit the dirty workspace.

Similar code exists here, which can be ported over to the sync.sh script to avoid these needless updates.
