This shows the commits in my branch starting from the most recent common point,
thus my commits, but I see differences in the files not explained by my commits,
but by the fact that many older commits (between v3.13 and v3.14) are missing on
my branch, but still in both branches I have a commit called v3.14 with the
same hash.  Is that normal ?
