But you have asked for an impossible state. You have said "this file
cannot have CR when you check it in, because we erase them". And yet the
version of the file in HEAD has CRs in it. So it must appear modified
with respect to HEAD.  And the solution is to make a commit with the
normalized content.

You said in your test script:

  # Committing test.txt or clearing .gitattributes does clear
  # the "modified" status, but those options are undesirable

Why is the commit undesirable? You have decided that CRs will no longer
be tolerated in your repository (by setting .gitattributes). Now you
need to record that change in history with a commit that strips out the

It is not about having CRs in the working tree file. Those are now
considered uninteresting and stripped by git when comparing to the HEAD.
The problem is that what's in your _repository_ has CRs.

I wonder if this is a fundamental misunderstanding of how the CRLF
handling in git works. It is not "magically make me not care about line
endings anymore". It is "the canonical version in the repo is LF-only.
Strip anything coming into the repository to match that, and
(optionally) add CR to anything going out to the filesystem for my
convenience". But you need a flag day to update the in-repository
versions to the new scheme.
