first-letter-non-punctuation-001 awkward

Hello public-css-testsuite,

 Test first-letter-non-punctuation-001 requires the user to tell a difference between a one pixel wide black line and a one pixel wide dark green line (a hyphen).

It would be easier to see if the text -T- was made considerably larger.
