commit 72fde6f made $pathToTest use Join-Path and in the process dropped the
fullname from $checkin. On my system, this had the negative of introducing as

leaves the path on the prompt an expected c:\path> instead of c:\pathPS>
maybe fix?
Implement describe style setting and functionality.
Fix branch name when in sync with upstream
