Are the semantics of --no-walk documented anywhere?
In the spirit of v1.6.4-rc1~3 (Make 'git show' more useful,
2009-07-13), we could make -n imply --do-walk.
This would change the meaning of git show -5 --all, so I am not too
happy with it.

Subject: DWIM 'git show -5' to 'git show --do-walk -5'
To show the last two commits with one command, one might try
1) git show -s master~2..
2) git show -s ^master~2 master
3) git show -s master^ master
4) git show -s -2 master
Choice (3) works because both commits are listed on the command line.
Choices (1) and (2) have worked ever since v1.6.4-rc~3 (Make 'git
show' more useful, 2009-07-13) disabled --no-walk in this case because
there is no other useful meaning for them to have. Unfortunately, (4)
does not work: it outputs only one commit, because --no-walk stays on.
So disable --no-walk in this case so ‘git show’ and future ‘git
cherry-pick’ can behave as expected.
As a side effect, this unfortunately changes the meaning of
‘git log --oneline --decorate --no-walk -5 --all’: instead of listing
five refs, after this patch that command would list the five most
recent commits.
