Hi,

I work on a case insensitive filesystem and I have core.ignorecase set to true. 
I have a series of troublesome commits and here is what git cat-file -p shows me:

...
100644 blob 99...	fourCircles.py
100644 blob 97...	fourcircles.py
...

The content of those slightly differ:

--- a/99...
+++ b/97...
-__version__='$Header: .../fourCircles.py, ...$'
+__version__='$Header: .../fourcircle.py, ...$'
 
As you can guess this git repo started its life with CVS (it was converted with git cvsimport). 
So I thought it was a job for git filter-branch, specifically I propose to do:
git filter-branch --index-filter 'git rm --cached --ignore-unmatch .../fourCircles.py' <commit>

However because of those two blobs, I have:

~> git status
#	modified:   .../fourCircles.py

and git filter-branch therefore refuses to run. I tried to use checkout, reset, 
even to commit that fluke of a change but whatever I do, that file is still marked 
as modified. 

I am sure I am missing a tiny detail that would get me
out of those dire straights but it has eluded me so far.

I run git 1.8.2.2 on MacOS 10.7.5 (installed with MacPorts if that matters).

Best wishes,

Luc J. Bourhis

Make a commit that has neither file, run git filter-branch, then throw
away the commit with git reset --hard HEAD~.

That did not work, i.e. fourCircles remained "unmodified". Eventually, I managed by successively removing the file with "C" and then the file with "c". Then filter-branch, and then reset --hard as you suggested. Then of course, all the sha's have changed and git cvsimport can't be used for incremental updates anymore, which I knew would happen, obviously.

Thanks,
