My local "800 line perl monster" basically does
    git ls-tree -r $commit_or_tag

which allows you to generate a list of files and their corresponding
hashes (it also helps with filtering out symlinks by the way).

The you can do
    git cat-file blob $commit:$path

or just
    git cat-file blob $hash

for every file you're interested in and parse the output of that file
(in memory, as it were). None of that messes with the current state of
the tree you're working on.
