In contrast, I suspect that recent Git for Windows versions have tons of
CR/LF-related fixes... ;-)

This smells very much like a problem I vaguely remember has been addressed
recently: Torsten Bögershausen was working on issues where files checked
out with one line ending, and then "retroactively" become dirty by
changing the line ending convention (which your -text seems to do) and Git
not really noticing this until the `reset --hard` call that simply cannot
cope with "this kind of dirty".

In essence, I am fairly certain that v2.12.2(2) should *not* display this
behavior.

If my hunch is wrong, please do fill out a full bug report at
https://github.com/git-for-windows/git/issues/new, preferably with a short
and sweet script to reproduce the problem elsewhere.

Thanks,
Johannes
