script for reproducing history example in git-log(1) man page

I wanted to be able to experiment with the TREESAME example given in the git-log(1) man page, so I built this script which recreates it:

--------- 8< --------- 8< --------- 8< --------- 8< --------- 8< --------- #!/bin/bash

mkdir git-log-example cd git-log-example

git init

# I echo asdf > foo; echo quux > quux git add . git commit -mI; git tag I

# A echo foo > foo git add . git commit -mA; git tag A

# B git checkout -b b I echo foo > foo git add . git commit -mB; git tag B

# M git checkout master git merge --no-commit b git commit -m"M: merge of A and B"; git tag M

# C git checkout -b c I git commit --allow-empty -mC; git tag C

# N git checkout master git merge --no-commit c git commit -m"N: merge of M and C"; git tag N

# D git checkout -b d I echo baz > foo git add . git commit -mD; git tag D

# O git checkout master git merge --no-commit d echo foobarbaz > foo git add . git commit -m"O: merge of N and D"; git tag O

# E git checkout -b e I echo xyzzy > quux git add . git commit -mE; git tag E

# P git checkout master git merge --no-commit e echo "quux xyzzy" > quux git add . git commit -m"P: merge of O and E"; git tag P

# X git checkout -b x I rm foo quux; echo side > side git add -A . git commit --amend -m"X"; git tag X

# Y git checkout -b y x echo side2 > side git add . git commit -m"Y"; git tag Y

# Q git checkout master git merge --no-commit y git commit -mQ; git tag Q

# cleanup unneeded branches git branch -D b c d e x y --------- 8< --------- 8< --------- 8< --------- 8< --------- 8< ---------

Would it be worth including this in (say) contrib/, and then referring to it from the man page, in case anyone else feels a similar urge?
