[PATCH v1 0/1] Teach status to show ignored directories

Our application (Visual Studio) needs to run git status with options to report untracked and ignored files. It needs all untracked files reported individually, but would rather not have all individual ignored files under explicitly ignored directories reported. Directories that match an ignore pattern should be reported, instead of all contained files.

It is not possible to get this output with the current arguments available to git status. You can get ignored files (--ignored), all untracked files (--untracked-files=all), but if you specify both options then you will also get all individual ignored files.

This change is to add the option to have git status report all untracked files while also reporting directories that match an ignore pattern. The logic in dir.c was also modified to not iterate over all files in an ignored directory. This change resulted in a performance improvement in work directories with a large number of files contained in ignored directories. For example, this setup is present when bin and obj directories are contained in the repository work dir.
