And if you use the Git Swiss Army Sledgehammer, a/k/a "git rebase", you can get rid of the commit with SHA x or, at 
least, not have it clutter your logs (as well as getting rid of all those silly merges Git forces you to do in some 
cases).  That's one reason why the "git rebase" in my "git update" script:

        git stash; git pull; git rebase; git stash pop

is handy.
