Re: identical hashes on two branches, but holes in git log

Trying to understand, I have eventually done "git log" on my branch and
on v3.15 with the following commands :

git log v3.15 --full-history --decorate=short | grep '^commit' > /tmp/3.15.commits
git log --full-history --decorate=short | grep '^commit' > /tmp/mybranch.commits

Either

    git log --oneline v3.15..HEAD ;# show what I have not in theirs

or

    gitk v3.15...HEAD ;# show our differences graphically

may give you a better picture than what you did, which was to
artificially flatten the topology and lose the crucial information
as to which commit is the parents of which other commit.
