I have updated the original version of this patch to encompass the
feedback comments obtained. Updates include:
1) Rename option to --no-index for consistency with other commands
2) Improved Documentation text
3) Extension to test scripts to include this option
Regarding test scripts I have scoped coverage to ensure correct
behaviour with the new option in all standard cases but without
duplicating every single corner case.
The original patch is at $gmane/233381.
check-ignore currently shows how .gitignore rules would treat untracked
paths. Tracked paths do not generate useful output. This prevents
debugging of why a path became tracked unexpectedly unless that path is
first removed from the index with `git rm --cached <path>`.
This option (-i, --no-index) simply by-passes the check for the path
being in the index and hence allows tracked paths to be checked too.
Whilst this behaviour deviates from the characteristics of `git add` and
`git status` its use case is unlikely to cause any user confusion.
Test scripts are augmented to check this option against the standard
ignores to ensure correct behaviour.
