Thanks for the reference. I thought it was a bit funny when I wrote the
above, but just assumed it was implementation defined.

I think it doesn't change our outcome, though. Even though we cannot
rely on the shell to do such an expansion, it is still probably not sane
to assume ls-files will do it. Git's expansion is connected with the
config entry, not the use in ls-files, and it is git-gui's
responsibility to correctly expand as it reads the config.
