[RFH] Finding all commits that touch the same files as a specific commit

["Sverre Rabbelier" <alturin@gmail.com>]

Heya,

Currently I do the following:
$git diff-tree --name-status --no-commit-id -r <hash>
To get all the files touched by the commit, I do:
$git rev-list HEAD -- all the returned paths here
This works perfectly, except when the subtree merge strategy is used,
since in that case I get (example from git.git):
$ git diff-tree --name-status --no-commit-id -r
5821988f97b827f6ba81dfeebff932067c88ba6c
M	git-gui.sh
M	lib/diff.tcl
$ git rev-list HEAD -- git-gui.sh lib/diff.tcl
$

Now it was noticed on #git that git log has a --follow argument which
-does- catch the rename, but it only works on one file at a time. So,
my question is this:
How do I find all commits that touch the same files as a specific commit?
I have described my current approach above, which does not work when
the subtree merge strategy is used. I am not stuck to this approach
though, if someone comes up with a better way to do this than with
'git diff-tree' / 'git rev-list' I'm fine by that. I provided with my
current approach in the hope that someone comes up with a similar
solution which means I'll have to edit less ;).
