Make links variable-width without underline

These are two independent changes.
- The monospace font used in links made the text larger so that less
  text could fit on the screen. It also suggested that all link text was
  an code snippet, which it isn't. The advantage of a fixed-width font,
  vertical alignment, was not put to any use.
- Underlining of links made it almost impossible to distinguish a space
  from an underscore.
