Add 4 test for the bash.showUntrackedFiles config option, covering all combinations of the shell var being set/unset and the config option being enabled/disabled.

We do not use "unset -v" anywhere else in our system. Shells mimicking SysV may choke on it. A Portable POSIX script can omit "-v" when unsetting a variable. Also "unset" can return false when the variable is not set to begin with with some shells. Neither of these matters for this particular case because we know we are running this under bash in non-posix mode. I however wonder if we can do something to prevent careless coders to copy and paste this piece when updating other tests that are not limited to bash. Commenting each and every use of "unset -v" does not sound like a good solution and perhaps I am being unnecessarily worried too much.
