I guess I'd really like to see git ignore all line endings of text files
in the repository. Text files would then never be marked as "modified"
for this reason and there would be no need to "fix" the line endings. I
think that should be the default, but just having the option would be nice.

In some cases it's undesirable. In my example, all I want to do is merge
in the change that deletes the file, so I don't want to have to add that
extra commit when I'm just going to delete the file anyway. It's also
very inconvenient to have to deal with this issue when you're in the
middle of a complex rebase operation.

Yes, but does that really have to be an issue? Is there any technical or
practical reason you can think of that the repository shouldn't ignore
those CRs?

You're right, we can't magically avoid all the line ending issues that
people will run into. In this case, though, I think git can sidestep a
fairly obnoxious problem. My example was simple, but when you've got
multiple branches that need to be rebased/merged, it can get pretty
hairy. The repository will never be truly "clean" unless you rewrite the
whole thing (using filter-branch, for instance).
Maybe my above suggestion is more of a feature request than a bug, but
there is the obvious bug that after changing .gitattributes, git still
doesn't notice that files are "modified" until you modify them again in
some way (touch works). I only noticed the CRs in our own repository
after I tried to rebase a branch and got strange errors. To make git
notice all the files, I had to "find . -type f -exec touch {} \;".
