paper/coal: use fixed width for diffstat +/- link
The plus and minus characters are normally not the same width in a
non-monospace font, and this made the line length change when the
diffstat display was toggled.
The square brackets are not rendered in a monospace font to ensure
that they align with the parenthesis on the same line.
