That doesn't seem to work.

For example, if I add '*.c' to .gitignores in git.git, I can't seem to
get that command to display any .c files.

Run on its own, it displays lots of files, but no .c files.  Run with
an argument (such as builtin-add.c), it displays nothing.

That also doesn't seem to do quite what I want, and probably in the
same way.  I see git add returns non-zero error status if a file is
ignored, so I can do it with

excluded=()
for f in $(git ls-files)
do
    git add $f || excluded=($excluded $f)
done

But that feels kind of clunky.  I feel I'm missing something basic
about how git ls-files is intended to work, or something.
