Isn't it better to display 100 * (a + W/2) / (a + W + b) instead?

This shows the portion of buffer before the window-center.  It will
show 50% in the first use case and 73% in the second.  IMO, showing
98% in the second case sounds misleading, not unlike the current 49%,
because it effectively disregards the text inside the window, and thus
can lead to skewed estimations when the part inside the window is
non-negligible relative to the part that outside.
