[RFC/PATCH] Add test case for dealing with a tracked file in an ignored directory

[Greg Brockman <gdb@MIT.EDU>]

This test case attempts to match the behavior of 'git add ignore-file'
with 'git add ignore-dir/file' when .gitignore contains entries for
ignore-file and ignore-dir.

This patch is a follow-up to the thread '[RFC/PATCH] git-add: Don't
exclude explicitly-specified tracked files' at

  http://thread.gmane.org/gmane.comp.version-control.git/153194

In this patch, I propose the desired behavior of 'git add' for files
contained in ignored directories.  I have attempted to mirror the
behavior of 'git add' for ignored files, but I may have gotten that
wrong or that might not actually be what we want here.  Comments on
whether this is the desired behavior and whether these test-cases
accurate capture that behavior would be appreciated.

Thank you,

Greg
