I changed mutt to not use M-F-T with the git list at all. Hope this one
turns out better.

Thanks; I meant to say "please do not redirect", but you got what I wanted
to say correctly.

The deletion of 2.txt appears lost during 'checkout -b foo', while the
modification and addition were both brought over. Is it a bug?

This behaviour is unchanged since early June 2005.

This is exactly the case marked as *0*, which both Linus and I said "it
feels somewhat wrong but otherwise we cannot start from an empty index".

We may want to do better this time around, though.

I have since found out that:

1. file deletions in the working directory but not in index would not be forgotten. That
makes "file deletions in index" case rather a corner one.

2. "checkout -b -m" would do the right thing.

Both correct.  1. does not involve case *0*; 2. does not do two-tree
switch but internally uses three-tree switch and uses different codepath.
