Frequently, I am looking for recent changes in a particular function. C-s in the ChangeLog is much more convenient than a git blame (or several of them in succession) followed by remembering the hash of an indicated change (or several of them), followed by a git show (or several of them). Let's please keep these individual function change descriptions in the VC log (which will eventually become the ChangeLog). -- Alan Mackenzie (Nuremberg, Germany).
