I came up with the following 'git-diffall' script to open all diff files
immediately, rather than default behavior of opening them one at a 
time in serial.

    for name in $(git diff --name-only $1); do git difftool $1 $name & done

I blogged the details at

You must have difftool.prompt (or mergetool.prompt) set to
false, otherwise git would be prompting you during the loop.

To make it work irrespective of the configuration, pass
--no-prompt or -y to difftool.


Also maybe something like:

for name in "$(git diff --name-only "$@")"; do
	git difftool "$@" "$name" &
done

The quotes should make it work paths that have spaces.
The "$@" should let you pass arbitrary parameters to difftool.

Have fun,

One last note (I promise ;)):

I would recommend against saying 'git difftool head' on your
blog beause that only works on OSX with its case-preserving yet
case-insensitive filesystem.  It might be worth mentioning that.

If you try 'git diff head' on a different filesystem (for
example, if you tried it on Linux) you'll find that it doesn't
work because the file is .git/HEAD; .git/head doesn't exist.

On OSX the filesystem tells git that .git/head exists even
though it's actually finding .git/HEAD.

Thanks David, understood and updated to 'HEAD'. 'head' had worked for me with my 
sloppy Windows ways ;)

I struggled with your previous suggestion for handling paths with spaces; 
I couldn't get the for-loop to split the input into individual filenames
on the line-break separator (after outer quotes expanded the result?).

But rewriting it this way seems to work well and handles spaces (Windows):

    git diff --name-only "$@" | while read filename; do
        git difftool "$@" --no-prompt "$filename" &
    done

Hope you can comment on this variation? 
And thanks for all the tips! Seba
