I just tried with the gcc repository with its about 100000 files. Here
it was about equal with ~30secs for both git and find. The git ls-files
invocation on the command line with output piped to /dev/null is done in
one tenth of a second.
Oh, when dropping the `expand-file-name' call we're doing on every file,
it's ten times faster (~3secs).
Bye,
