This may have little sense in a general case as the history maintained
by Git is a graph, not a single line. Hence your prospective approach
would only work for cases like `git log` called with the
"--first-parent" command-line option.
Still, for a simple approach you may code it right away yourself.
Say, let's create an alias:
$ git config alias.foo '!git log "$@" --pretty=oneline --source | {
n=0;
while read sha ref rest; do
printf "%s\t%s~%s\t%s\n" "$sha" "$ref" $n "$rest"
n=$((n+1))
done
}'
Now calling `git foo --abbrev=commit` would output something like
9be8e297d HEAD~7 Frobincated fizzle
where "7" is what you're looking for.
A more roubst solution may need to use the `git rev-list` command.
