changelog: avoid cutting off commit messages Split commit message into 2 <div> elements: one with just the first line, and one with the full message. This makes it easier to handle the toggling of showing the whole commit message. This way, we no longer have to mess with the line height, and we avoid problems with cutting off parts of the text below the text baseline. Also stop cutting off the first line if it is too long for the table column. It adds a bit of overhead to store the first line twice, but having them separate make things simpler and is worth it. Patch modified by Mads Kiilerich.
