Assuming that the last step of what Horst did was "git commit -pm",
I think Git is wrong in this case. When you tell "git commit" what
to commit, unless you give "-i" (aka "also") option, the command
makes a commit to record changes only from what you tell "git
commit" to commit, regardless of what you earlier did to the index.
And choosing what to add via the interactive interface is in the
same spirit as telling what to commit to "git commit", so it should
behave the same.
This is one of the times I wish I said "No, you cannot have a pony".
The change was done without thinking things through, and reviewers
including me did not realize this particular downside. My accepting
this misfeature (or a poorly implemented feature that has a
potential to be useful) was essentially me saying:
When making a commit that does not match my working tree state,
I always check with "diff --cached" to make sure what I think I
am committing matches what I am committing, so I won't use such
a lazy option myself. I am not excited to think things through
to see what possible pitfalls the feature may have for you; I'll
let you guys hang yourself with that long rope.
And we are seeing a backfire from that "not bothering to think
I think the right thing to do is to fix "git commit -p" so that it
starts from the HEAD (on a temporary index), just like how partial
commits are made with "git commit file1 file2". Or just forbid it
when the index does not match HEAD.
