There is not one answer to "which commit"; there may be an infinite
number of commits which merge it into something else. The best you can
do is start at some point (e.g., the tip of "master") and walk backwards
looking for commits which merge it (and you still may find multiple, if
the commit was merged into two other lines of development, each of which
was merged into your starting point). There is not an option to do this
search automatically, so you would have to use grep, like:

  git log --format='%H %P' |
  grep " $commit" |
  cut -d' ' -f1

which will list the id of all commits (%H) for which $commit appears in
the list of parents (%P).

   "git tag --contains" and "git branch --contains" useful.
