OK, and if I say "git add subdir/a-ok" I get no error, as expected.

So extend it just a tiny bit, moving a-ok down a directory and using the negative pattern "!subsubdir/a-ok" to match:

    brs% cat .gitignore
    a*
    brs% cat subdir/.gitignore
    !subsubdir/a-ok
    brs% find *
    all-files
    subdir
    subdir/.gitignore
    subdir/subsubdir
    subdir/subsubdir/a-ok
    subdir/a-ok
    brs% git ls-files -o --exclude-per-directory=.gitignore
    .gitignore
    subdir/.gitignore
    subdir/subsubdir/a-ok
    brs% git add subdir/subsubdir/a-ok
    The following paths are ignored by one of your .gitignore files:
    subdir/subsubdir/a-ok
    Use -f if you really want to add them.
    fatal: no files added

So I think the output from git-ls-files is as expected (as I interpret the manpage and your explanation). So is git-add just using some different code?
