A bug or a feature (git diff --author + --grep)

I would have expected the --author and --grep option to work as pipeline filters. The first on the command line being applied first.

In other word I would have expected:

    --author AND --grep

But it turn out that the result are maching either --author or --grep:

    --author OR --grep

For example on the Git project:

    $ git log --author=obry --grep=Cygwin

Returns commit from obry and commit having Cygwin in their log.

Is this a bug or a feature?

Thanks, Pascal.
