I think combining some of those 400+ :first-letter pseudo-element
tests is a good idea, but can we break this up so that it's not
all one huge file? One of the criteria for CSS2.1 tests is that
they have to be *short*: the goal here is to test :first-letter
correctness, not to stress-test mobile devices.

Another problem is that the file is not valid XHTML. (It's not
even well-formed XHTML.) The build scripts will choke on that.
Also, it appears from the source that this is a visual verification
test, but there are no instructions.

Using a script to generate this test is fine; we have other tests
that need a pre-build process. But the other three issues make the
test unusable as-is.
