My additions are for running commands (i.e. running the necessary
hooks in hopefully correct order) and for testing of fontification.
There is also a little bit for adding a test input file for a test.
And a bit for keeping track of the test name.

But I suggest you review my code and tweak it to your liking. Please
contact me off list.

There is already a sub-directory for tests, "emacs/test". To my
surprise the elisp files for test also is there. I suggest these
should be somewhere like "emacs/lisp/test" instead and that
"emacs/test" will be for data files etc instead.

An objection to this might be that the tests can't be run without the
data. Yes, but the code in the elisp files can serve as examples for
those writing tests.
