[PATCH 00/40] test whitespace - perform trivial whitespace clean ups of test scripts.

The series applies cleanly to both master and pu.

The first patch contains a script, t/test-cleaner.sh, that can automate whitespace cleanup of tests. The remaining patches are the result of running the example.

For example:
	cd t
	./test-cleaner.sh fix-whitespace-auto t[0-9]*.sh

will:
	* identify test scripts with trivial white space errors
	* edit the test to remove the trivial white space errors
	* verify that edited test produces same outputs, errors and exit code
	* creates a single commit for the edited test

fix-whitespace-manual will do the same for tests that are broken by the edit. 

In this case, the commit message is prefixed with FAILED:

These scripts rely on the existence of expand and unexpand on the PATH.
