Some colors from the current `vc-annotate-color-map' are
illegible when used for a foreground on a light background
(white by default).

But the last patch provides a palette where color saturation
is reduced from 75% to 20%, so the output looks nicely
for light backgrounds where related lines are grouped
using the same backgrounds like in the table from this post :-)
