You "clip" an entire page, and I think this is still true on the Kindle 2. However, highlights also appear as text in your clippings file.
On the Kindle 1, the on-screen highlighting is a box around the lines in question. The selection is for whole lines, but lines depend on the font size (and perhaps how you reached a spot in the ebook). The on-screen box is always entire lines, and it seems to always include the highlighted region but may include extra text to pad to a full number of lines.
The grey underline on the K2 gives you finer control of the underlining, but may not be as visible as the K1's box.
