Squashing commits with git rebase -i may miscount commits in commit message

git --version: 2.11.0

When using git rebase -i to squash a series of commits that includes more than 10 commits, the generated commit message you are given to edit counts the old messages incorrectly. It will say the total number of commits is (actual % 10) (if they were 0-based) and it will also count the commits as (actual % 10).

For example, 15, 25, 35, etc. commits: # This is a combination of 5 commits. # This is the 1st commit message: msg

# This is the commit message #2: ... ... # This is commit message #10: msg

# This is commit message #1: ...

# This is commit message #5: msg

While not a big issue, it did make me double check what I was doing when I saw "a combination of 10 commits" instead of 20 in the commit message.
