Subject: [PATCH] '%S' option for pretty printing to support --source
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit

Print out the ref name by which each commit was reached. Works only when --source option is used

Examples:

git-log --graph --pretty=format:"%h(%S) — %s (%cr)" --abbrev-commit --date=relative --source

Show ref by which each commit is reachable in current branch

git-log --graph --pretty=format:"%h(%S) — %s (%cr)" --abbrev-commit --date=relative --source --all

Show ref by which each commit is reachable globally
