Me being the reporter of the original msysGit issue #177, I'd like to
clarify that my intention not necessarily was to make
"core.autocrlf=true" affect temporary files (i.e. to "smudge" them),
but to ensure that the files fed into "git diff" are always generated
/ acquired in a consistent way, so that they are in fact comparable.
I'd also be happy with a solution that always feeds clean files into
"git diff", although that would probably mean that we could not reuse
working tree files if "core.autocrlf=true" is set.

Maybe it's a good idea to look at how gitk displays the diff, for an
orientation. If the diff gitk shows is based on smudged files, git
diff should probably also always be fed with smudged files, and if the
diff gitk shows is based on clean files, git diff should probably also
always be fed with clean files.
