Describe what symptom you may see if it is left unfixed.  IOW, if we
consider that having a whitespace in the path to the build directory
is just as crazy as having a single-quote, it would make this patch
unnecessary,  Make it easier for readers to decide, by saying
something like

	As TEST_DIRECTORY is (typically) path to t/ in the extracted
	source tree, it can have funny characters like $IFS whitespace
	in it.

at least.

Thanks.
