[problem with name-rev] (was: git log --graph with a sort of local revision number)

   > You can achieve something close (on small repos, more on that later) with:
   > $ git log --graph --color \
   >   --format='%C(auto)changeset: %h:%H%nuser:      %an%ndate:      %ad%nsummary:   %s%n' \

It seems that there is problem with name-rev.

Here's what I get when I start committing on master, then switch to a branch foo and finally merge foo into master:

git init echo 1 > 1 git add 1 git commit -m 1 echo 1.1 > 1 git add . git commit -m 1.1 git checkout -b foo master~1 echo 1.2 > 1 git add . git commit -m 1.2 echo 1.2.1 > 1 git add . git commit -m 1.2.1 git checkout master git merge foo echo 1.2.1/1.1 > 1 git add . git commit -m "1.2.1/1.1"

Then 
 git log --graph --color --format='%C(auto)changeset: %h:%H%nuser:      %an%ndate:      %ad%nsummary:   %s%n'   | git name-rev --refs=$(git rev-parse --abbrev-ref HEAD) --name-only --stdin | more

That looks odd.

Any comments?
