fix: git-summary commit count

[xwjdsh]

If the user has set log.showSignature = ture in gitconfig file, then the commits field in the git-summary result is wrong. Replace git log with git rev-list to avoid the problem, git rev-list isn't affected by log.* config parameters, which is also the same as git-count command.

---

The result of git log --oneline HEAD is as follows, then | wc -l | tr -d ' ' get wrong count.

We pass --no-merges via $MERGES_ARG. How could we handle this with rev-list?
