This seems like a special case that Git could detect and message about
somehow.

Yeah, I read the docs, but the oddities of reset not doing its job
wasn't clear from this sentence :) .

The fact that plumbing is necessary to dig yourself out of a hole of the
`eol` attribute changes points to something needing to be changed, even
if it's only documentation. Could Git detect this and message about it
somehow when `git reset` cannot fix the working tree? Or maybe it could
at least exit with failure instead of success?
