[PATCH 4/4] Make test-lib warn if the directory changes.

["Sverre Rabbelier" <srabbelier@gmail.com>]

From: Sverre Rabbelier <srabbelier@gmail.com>

If a script moves out of it's directory, but thereafter
does not move back, the test results would not get written
to the proper file, as such, remember where we start at
and then later on, write to that place.
Also, if it is noticed that the directory was changed,
issue a warning.
